I feel like what i'm feeling all the time is depersonalization. When I read up on depersonalization, I can relate a lot to its description and symptoms, such as feeling disconnected from my environment, feeling inside my head all the time (not feeling like I'm in the present), feeling like I'm in a dream, feeling like a zombie, like I'm there but not there at the same time, sometimes feels like I am looking through life in 3rd person or as someone else, my hands and arms feels like it could be someone else's. 

From doing a quick google search, the medication Desipramine was suggested. Let me know if you have had any experience with it, or if you've had any experience with depersonalization and what you have done to help it.
