If i don't have morphine, clonazepam, lamictal, risperidone, bupropion and often weed i don't feel right either. You sound like your on self destruct mode right now and ive fucking been there more then a few times and i'll probably be there again. But nothing stays the same man the bad passes with the good. Things do fucking get better.
Talk to someone if you have a friend or anything call them up. That has helped me get through many a long night. Call a suicide hotline or anything in your area if you need to. Also as one who suffers from manic episodes as well as mixed episodes and depression i can say that amphetamines don't fucking make you feel better! All they do is fuel the feelings your already having weather good or bad. Ive litterally sat down at 4 in the morning high as a kite on dextroamphetamine crying my fucking eyes out do to thinking about all the shit thats going through my fucked up head because everything seems so much worse when your on amphetamines. So i would suggest maybe atleast cutting back on that. Also if by ice you mean meth if you think you feel bad now wait until you come down from that.
Just try and take it easy man
