Sometimes I think its just a cycle. I go through some weird stuff sometimes that seems unrelated to diet or exercise to rule out the obvious. As for
illness, depends. Sometimes its like something keeps pulling me out of sleep.
Anyways, if you experience sleep paralysis and are looking for a paranormal explanation, sometimes resisting the process of an astral projection can
wear you out like that. And of course there is the possibility of being drained or manipulated externally. I've had one day where from the moment I
woke up I just wanted to die. I didn't realize it at the time but in terms of meditation, all of my chakras were completely blocked and closed.
You could also be iron deficient. I was always tired until I realized I was anemic. I eat lots of iron enriched foods and get lots of Vit C, which
helps with iron absorbtion. That really really helped my energy levels.
I'd suggest getting iron in ya, with some Vit C and all the rest you can. You could be ill.
There was this one week a couple years ago where I didn't feel sick but I just had NOOO energy. I'd lay down and feel fine, but it was a struggle to
move. Keep in mind, there was a flu or something going around, and the day before that I was wandering around in a sewer drain pipe! But yeah.. it
lasted a week, but it was like you describe.
I'm no doctor but hell, i'm an alternative healer in training, just get some rest dude! Rot away and watch tv, or meditate or something if you know
how, it really helps to maintain your health, you can even learn to heal yourself.
Check out Dr. Bruce Lipton's biology of perception vid on youtube. He talks about how stress and fear have a decaying effect on your body, allowing
illness to do its thing, and alternatively just commanding yourself to get better, and feeling healthy mentally speeds up the recovery process. It
works man. Last time I had a nasty cold it only lasted 2 days compared to the usual week.
Anyways, someone here said you could have mono or something.
Get well dude.
