So I tried Lsd with my two friends for a first time like 3 weeks ago. At first everything was going alright, we were laughing a lot and had much fun watching all the visuals we had. Then I decided to drink some beer (which I don't drink at all) and it tasted like lemonade so I drank like one liter of it like in 15 minutes. After that we went to smoke some weed (I was heavy smoker, so I didn't even think that bad stuff can happen). After we smoked a joint, I got crazy and started to think things like that life is a simulation and that we are all being controlled by someone. I started acting weird and I felt like I was being controlled by someone at that moment and felt like I was out of my body. Like 10 minutes passed and I came back and my friends were looking strange at me like I was crazy and this idea that I went crazy got me very anxious and I couldn't get rid of it. I couldn't stop thinking about this crazy stuff that I somehow damaged my brain and my whole trip was turned to a bad one. After like 10 hours I was feeling even more depressed and couldn't even go to sleep till the morning. After I woke up I was feeling the same way and this even got me more anxious. I could not get rid of all the bad thoughts and I felt chest pain. Few days passed, I smoked weed and had a panic attack (which I even thought was heart attack). I went to hospital to check my blood and doctor told me that my potassium level has decreased. I was relieved that this was not something more (like brain damage or something). I started to eat healthy, stopped smoking weed for a few days. 4 days passed and I decided to smoke some weed again since I was getting better. After that joint I started to feel very paranoid, felt chest pain again and was getting thoughts that this is some kind of schizophrenia, I was like in mini Lsd trip. So I completely stopped smoking weed (which I was smoking daily like 5-10 grams a day) and few days ago I was looking into some flowers and I saw it shaking. My heart started beating again, anxiety got me again. I was trying to calm my self down and it worked for that day. The next day I woke up and felt like high on Lsd without smoking weed. Now 3 days passed and I still feel the same feeling and I think that it is getting worse. I started to see some kind of lsd trails everywhere I go and I am wondering if this is HPPD?I sometimes see a wall breathe or move and also I see some kind of flashing lights ( I don't even know how to explain, it is like I would watch at the sun for a minute and then turn my head from it and see the sun image on the wall or everywhere I look) and this thing won't stop. I checked my brain with magnetic resonance imaging today and doctor told me that everything is okay with my brain so I am getting paranoid that this hppd thing is starting to kick in. I now feel like my life is pretty much over or ruined, because I read that you can't cure this thing. My mood is changing very fast and I feel somehow empty in this world right now. I need help and I don't know what to do, I feel sad. I am 22 year old male. Thinking about hppd even get these symptoms worse, but I don't know how to not think about it since it disturbed my life so hard.. I am getting really crazy about this and I am worrying that one day if this won't stop I will do something bad to myself..
Sorry if I made some mistakes, English is not my native language. Does anyone have advice what should I do and how should I control my mind so I could worry less about this stuff. I would also like to know if this is hppd or something else if someone could tell me.. Since I am writing this and thinking about hppd it started to feel like it is kicking very hard right now, I feel very worried shit..
