I've smoked cannabis for 7 years (14 when I started) from 16 onwards I took ecstasy most weeks up till I was 18 from then I tried magic mushrooms about 6 times first few times I had a good trip then I took them again on Halloween of 2016. From December I ended up having the feelings of vertigo so I took all the pills the doctor told me to but nothing changed... so I have been put on xanax and anti-depressants things are still the same. My symptoms are of a wobble feeling through my body, floaters, sensitivity unstable feeling when I look around... I'm finding it really hard to wrap my head around things and just feel very lost... my real question is, is this a form of hppd that I'm having?
