I've had depersonalization since I was 15, I'm now 28. How can I get rid of this?

When I was 15 years old I started to get these random feelings of not being myself, like I was watching a movie or tv. This really irritating disconnected feeling I cannot get rid of. I don't even feel like I'm living because I feel like I'm not really here. My parents tried to get rid of the fact I like members of the same sex when I was a kid so they had psychiatrists drug the crap out of me (anti depressants, anti anxiety etc and they all backfired). I'm 28 this year and it's getting worse, I'm barely feeling there. Dreams feel more real that being awake. How do I get rid of this? And no medication, whenever I take anything I ALWAYS get the adverse effects and they never work. Plus I don't trust them.
