help yall

i used to have this with hallucinations when i was about 12 years old. i was really into those edgy deepweb videos back in the day, and i was genuinely convinced that a tall shadowy figure was stalking me at night. and every night, hed come a little closer to my bed. and that guy that everyone sees in their dreams? i saw that guy IN REAL LIFE. staring at me from the corner of my fucking room. and NO ONE BELIEVED ME. i didnt tell anyone at the time, but when it started getting closer to my bed every night, i started freaking out and i told my school counselar. i did eventually go to a psychiatrist, who told me i believed in the horror stories i read and watched, and thats why i imagined them in my room. i didnt have it for a year and then last year i started getting those hallucinations again but this time it was auditory hallucinations. it would be voices like my mom or a random classmate shouting gibberish in my ear and because of that first time i hallucinated figures in my room my mom just told me i was imagining it. it eventually went away, but damn was it a pain to deal with when it was around. i was paranoid all the damn time, sometimes they were so loud i didnt hear the words that came out of my own mouth, which resulted into me saying random words in hopes it would form into a comprehensable sentence. this happened especially when i was infront of a group of people, like giving a presentation. when i talk to friends i was able to block them out a bit since i was in an active conversation, but when i was standing infront of a group of people, it was just me, a quiet room, and my mom screaming gibberish in my ear. the stress of doing a presentation didnt help with it either. when i was 12, i also believed that everyone i ever knew and loved was sitting in a room, watching what i did everyday through a small camera. i was terrified to shower, to go to the bathroom or to even change clothing. i had that fear for the longest time, probably until i was 14. during those times, my house wasnt in its best condition, and there would sometimes be bugs in my bed. not often though. but finding that one bug on my pillow that one time triggered nights full of feeling bugs crawl up my legs. i would be so tense that my calfs would sometimes cramp up. i dont have these things nowadays, though ive noticed they come back every two years. im not allowed to go to a psychiatrist anymore since the last time wasted alot of time and money because all he said was that i was ewatching too many horror movies. what should i do?
