Drug rehab center symptoms and conditions

Heart racing so much I can hardly breathe. Nausea beyond belief and vomiting, feels like my head will explode, insomnia, nightmares, sweats where I am drenched from head to toe......to name but a few. I'm on this website because my Doctor tells me it's not the medication and I know it is. I've been on 3x75mg per day and have weened myself down to 75mg a day over the last year but side effects are getting much worse. Feel like I should take myself to hospital but don't think I can get there. Depression was bad enough but now I'd rather not be here at all.
