 Im not asking for anyone here to diagnose me, i just want to know your opinion what does this seem like to yall. 

I heard when you have psychosis you are unaware, but idk im maybe just overthinking stuff. Everytime i walk my dog i start to think cars are following only me and everyone wants to follow/kidnap me. Like, everytime a car passes my mind goes "why did you slow down THERE where i am, do you want to assault me or something?" sometimes i have fear sometimes annoyment. I also believe whenever someone passes by me doing something they do it on purpose and want to look at what im doing. I've had social anxiety for a long time but never experienced something like this. I usually don't trust anyone and i had a few tiny hallucinations like something being larger or smaller or some tiny lights appearing. I also once put a knife in its place but my mom found it in the trash, im fearing i hallucinated putting the knife in the shelf maybe? I've also had this hallucination at 11 but i had no symptoms. I feel like im overthinking. Also everytime i walk my dog, this man ALWAYS goes out on his balcony even if im super quiet and leaves when i move out of his view. I once saw him recording me from his window, i think, but i know he moved. Idk what does this all mean maybe im just overthinking maybe it's real. I also do have some derealization symptoms and believe nothing is real but that's another thing.
