I'm confused whether it's recommended to seek help for this

I'm a 16M, got immigrant parents that have their not correct opinions on psychiatry/mental health. Kinda just want to run my issues by y'all and see if they're normal bc I have no frame of reference. I always feel like I'm being watched, even if I'm alone. I sit facing away from the door into my room when working, and I can't even go 2 minutes without turning around because I feel like I'm being watched or someone is there. Every night I check EVERY single place where a human being could plausibly fit. Behind curtains, under beds, etc. In the past 2 months, I've completely stopped wanting to go out or do anything, although I still behave normally at school and am social when I am already out. Whenever I look into a vent, there is a face; not fully detailed, but there, staring at me. I also always see the edge of a silhouette, especially in shadowed areas. I have also gotten REALLY tired over the past few months; regardless of sleep, I feel DEAD until like 3 pm. Also have a weird thing with making sure that a few certain items in my room are perfectly aligned. And with the checking everywhere I mentioned previously, it's not just open the door, no one in there, close door. I have to feel my eyes focus on every corner of the room before I'm good. What do y'all think.
