As an ex-Wiccan, and (VERY) occasional spell caster, I can offer this as advice. My disclaimer is this: These are my beliefs. It makes me sick when
people state something regarding the metaphysical as fact. So, when I say X=Y, just please understand that it is my opinion.
That said...
Magic is not only not a toy. It's not even a good tool when it comes to the vast majority of situations. Anything you can accomplish with magic, you
can almost 99.9% of the time manage to do mundanely, with a lot less effort and backlash. Casting a spell for reasons as (IMHO) stupid as to be numb
to emotion is not only immature, it's overkill to the point of trying to use a small tactical nuke to rid your home of roaches. What she needs is not
a mirror book or a wand, what she needs is a therapist.
Unfortunately, it's real easy for me to take that point of view
now, since I'm a more than a decade older from my first big huge mistake.
I'll relate the story, if you care to hear it, but otherwise, will continue onward.
This is something that it seems like a lot of first-time, or early-on magic practitioners make. It can be likened to a med-student and the first
patient they make worse instead of better. It's a learning experience, and should be taken as such. It should also be taken as a very big red
flashing warning sign that she needs to be a lot more judicious about "what she wishes for."
Now before I give the cure, I'm going to give the lesson.
Magic has consequences. Huge consequences. In normal everyday life, when you perform any action, it sets in line a chain of events that go beyond all
comprehension or prediction. Take for example, the choice at a soda machine, between Coke or Dr. Pepper. If you choose a Coke, there is one less can
in the machine. This means that someone who approaches it may find it empty of their preferred brand, and end up losing their 50 cents, and are now
deprived of the caffeine which gave them just enough of a jolt of energy that later that night, they might have responded more quickly to the guy
driving recklessly on the freeway. Instead, they die in a wreck. If you choose the Dr. Pepper, it may turn out the die-hard Pepper-fan decides to
visit another locale that they might not have visited otherwise. Perhaps it is a convenience store, and there they meet their true love, or perhaps
they get shot by the guy robbing the place. Is this all directly your fault? No. But your actions set in motion a wave, that reacted against other
waves, to result in a unique end.
Magic takes that and multiplies it by a huge factor. Energy does not just appear and disappear at will. It transfers. It has to come from somewhere,
and it's going to tend to go towards the path of least resistance. When you use a spell, you are specifically altering the paths to create less
resistance towards your desired goal. Meaning, you've changed the momentum of the world around you, to suit your goals. So, for instance, if you
wanted to bring rain to your crops, and cast a spell, you may end up, as a result, causing a killer ice storm in another area, which takes the lives
of many people in the resulting chaos. Or you may end up causing massive drought in another area, causing many people to lose their livelihood.
You've taken weather patterns that would have otherwise had a different result, and lowered the resistance in just the right areas so that it suits
your needs... and as a result, you mess up the natural flow.
This is why it is so very important to not cast capricious spells, or selfish ones, or really, to cast unless you absolutely have to. The
comparatively miniscule payoff is not worth the consequences. I have reached the point now where I won't even cast a spell to heal someone dying of a
slow and painful disease, because I don't want to invoke the consequences of playing with life and death. I can't even think of a "good" reason to
cast at all, right now, to be perfectly honest.
Secondly, Negative Emotions like depression, anger, and fear are natural aspects of human nature. They are neccesary in order to appreciate what is
good in the world around you, as well as to help us survive adverse situations. They are the result of glandular excretions, and are no more supposed
to be blocked than the natural production of insulin, hemoglobin, or other such things. Your friend sounds young--I'm guessing adolescence. If she's
experiencing harder times than she has in the past, it is most likely due to hormone imbalances that are typical for every teenager. My best advice is
for her to suck it up and learn to deal with it, because life doesn't get any easier in the real world. There are no happy fairy tale endings, and
the good times will not roll forever. A good life takes hard work, and oftentimes, some pain.
Now for the cure.
First, she must come to terms with what I have just told you. Otherwise, all this will do is address the symptom, and not the real problem: an
irresponsible use of magic, and a lack of comprehending the consequences of using it. Before she ever casts another spell, she needs to come up with a
code of ethics on its use, memorize it, and always be ready to add to it. She needs to figure out what she's willing to literally kill for, because
when one casts a spell, there is quite possibly the chance that someone will die, somewhere, as a part of bringing in to being that desired end.
Second, she must come to grips with the fact that sometimes her body will be physically, mentally, and emotionally out of balance. It's not something
to be altered with magic, it's something to be dealt with the good old-fashioned way: by
cowboying up.
Finally, this is the counter that I would personally recommend.
Start it off with a meditiation. She should attempt to clear her mind of anything and everything, and reach some sort of inner peace. Some people
visualize a candle flame, and send all their thoughts towards it, others use a light of some sort to engulf them... she sounds like the bitter type,
so the candle flame may be best. Personally, I visualize a shape that grows more complex (starting with a dot, then a line, then a triangle, then a
square, etc...). Whatever works, her mind needs to be clear, and she needs to keep it that way for the rest of this.
Next, have her fill a tub, mixing and dissolving a large amount of salt into the bathwater. Salt is typically a very cleansing element used in magic.
She will need to visualize each individual grain of salt flaring up when it comes into contact with energy, dissipating it. Have her think of the salt
as rubbing alcohol on germs, except instead of germs, it's energy.
It would be a good idea for her to have a small snack standing ready, perhaps some milk and crackers or some such. If it works, she will probably be
exhausted and ravenous.
Next, she should submerge herself completely in the bathwater. Hair and all, and visualize the salt flaring up as it comes into contact with her body.
The salt will use her energy as fuel. She should then tense herself up, as tight as possible, sink beneath the surface of the water, keeping every
muscle flexed as tight as she possibly can, until it begins to burn.
As all pain receptors go to the spinal cord and medulla oblongatta, she should visualize the previous spell as a series of webs, spidering outward
from it. THE SPELL SHOULD CONSTITUTE THE WEBS, NOT THE NERVE PATHS.
As the pain from tensing begins to burn, imagine the tension snapping those webs, and the heat melting them, the now loose energy floating upwards,
out of the skin, to be burnt up by the salt. Once the webs have been removed, have her let out a primal roar as she rises up out of the water, before
relaxing. This will not only clear out any "bad air", but the act of screaming can be a huge relief sometimes.
Next, rinse off the old salt, using the shower, dry off, eat the snack, and go to bed. For some added effect, she may want to sleep on totally clean,
fresh sheets.
I hope this works. If it only works partially, have her try repeated times. If it still doesn't work, then the Powers That Be have other reasons in
mind for giving her this effect. And perhaps it is to teach her the value of trying to keep a positive mindset in the face of adversity.
