The most important thing is to go to a rehab facility and detox from the drugs...drugs are very bad when you have mental health concerns. It is hard to tell if you really have a mental health diagnosis or if it is the effects of the drugs you are taking that are making you that way. I would consider psychiatric hospitalization as well since you said you have lost touch with reality. If you are in a hospital they can monitor you and get you started on medications. You should be able to have therapy daily and meet with the psychiatrist daily (at least in my state you do).

I wish there was some magic word or response that would make everything better but there isn't. I am sorry you have to go through this and please keep posting...there are a lot of wonderful and supportive people here that will help you when needed!
