Blocked in

I a blocked in at all angles: too depressed to do anything, too anxious around people to have any social contact, although I am painfully lonely, too pessimistic to see anything good, too high strung to ever relax, too damaged to function, and I feel sick all the time, my head and stomach always burning, I always feel nauseous and dizzy. Yet I never seem to be able to manage to kill myself. Every method I have available seems bad. I have tried everything, meds, acupuncture, bath salts, exercise, ect. Even the doctors I go to ask me what I think there is left to try. I want so badly to fix my stomach problems, and whatever the hell is wrong with my head, but countless doctor visits with no answers about it leave me hopeless
