Hallucinations— i might actually need professional help

I've been stuck in this state for months, maybe even years.. i have to sleep at the very corner of my room, i constantly feel as of something/someone might be watching me, I even get fuckin sleep paralysis here and there... I have to have a working fan next to me or I'll be waking up DRENCHED in sweat Is this like, a normal experience for ppl with untreated autism/depression or am I going bat shit insane. My heart genuinely doesn't feel correct gng, it's been beating like crazy...! (P.S. I don't do any substance abuse, I'm way too young for that brah)
