I was wondering if I have paranoia or something similar, there's a couple of behaviours that I've now realised maybe aren't completely normal. If they are however then that's good I guess

I'll list out the behaviours I mean below:
- Every job I've had when co-workers or my boss were talking quietly or looking in my general direction I've always been convinced that they were talking about me
- I often doubt my friends and if they're loyal to me
- When it's dark if I'm outside I'm constantly on edge (that might be thanks to movies though)
- I don't really have an "angry mood", I suddenly get very angry out of no where and 2 minutes later I'm better
- I seem to crave acceptance
- A lot of the time I can't keep still, I have to be moving my leg or fingers or something.
- Sometimes I see things that aren't there, not really detailed but sometimes just black figures or outlines for a second or two. Yesterday I went to bring the phone up near my ear and for some reason saw what looked like a mosquito right in front of my face out of no where and it made me jump? I have no idea what that's about, maybe that's an eyesight thing
I appreciate any replies and thoughts, I'm just trying to figure out if I have something. I was going to post this in the paranoia section but then thought I wouldn't seeing as I'm not sure what it actually is.
