My perception does not feel like reality

About a year ago I took LSD and had a bad trip. I took two tabs and got sent to the hospital, my mind for the whole trip was in a sort of auto pilot mode. And the thought of me having a sad life accured. I was not sure if it meant I was having a sad life or was going to have a sad life. I never took any after that but continued to smoke weed. Recently I smoked and had a sort of panic attack. My body shook uncontrollably sweating and I had the feeling my perception was altered. And I felt like everything happend before (i.e déjà vu). I was feeling like life was a game, or a simulation of some sort. I also was hearing beeps like I was in the hospital. The beeps continued for about 3 days, but the thoughts are still here today. It has been about a week. My perception does not feel like reality. Life feels like a game or simulation and my fate has already been decided but it is unknown to me. I did reserch and it sounds like Depersonalization disorder but I'm not sure. Everything and everyone is some sort of trap in this game I am playing. Help please I don't know what I'm going through. I'm just 19 and going to school right now.
