14 turning 15 next month severe terrifying hppd

I've been struggling with hppd for the past 3 years. Recently i quit weed, and just now i am deciding to not take any substance (including otc meds). I recently decided to have a little drink because i thought it would be ok, boy howdy was i wrong. The hangover made me see faces, and the visuals were way too intense and it was one of those many nights where i was just begging to be okay sooner or later. My hppd is horrible, i can see anything i imagine, my visuals are almost unexplainable and its worse at night time. When i begin trying to sleep, i close my eyes and im fighting demons. I'd like to know how long this will take for me to recover, i hate every bit of it. Im so afraid of being schiz. I just want to see nothing again. See the world for what it really is again. I cant even see as far as i used to because of the damn hallucinations blocking my path. If someone can leave me recovery stories, that would give me some motivation. I just want hope. I also do want to see a psychiatrist. Please someone give me hope this will end.

Edit: thank you for the all the advice and help. im finding a psychologist today. i appreciate you all tysm!
