Regression

I've been just one single week off pills (for various reasons I'm too lazy to write right now) and I have whitnessed absolute regression, I'm back exactly where I started...
I can't eat, I can't sleep at night so I nap A LOT through the day. I can't study, get out of bed... anything. I feel like crying all day long and I cut just to be able to deal with being awake. I'm scared of waking up the next day and as soon as I do I can't wait for the day to be over already. When I look into the future I can't help it, I just think "I'm not sure I want to live through that".
Damn it, wish I could just die already.
Sorry this is so depressing.
Don't even know if I'm making any sense here.
