Are there potential mental illnesses I should research and talk to somebody about? This post is in no way for somebody to diagnose me, but I don’t know if any of these things are related to one another, completely normal, or due to separate issues. I have quite a few “things” that I don’t know whether or not they’re perfectly fine or mental illness related.
To list some of them, in no particular order:

Sometimes I can’t exactly differentiate between my dreams, my actual life/reality, and scenarios from my thoughts. They all get confused in my head and I can’t tell which is which.

Each side of my body must feel “symmetrical” (If I hit my left hand, I’m compelled to hit my right to make them feel the same)

I constantly shake and get overwhelming anxiety from certain things. Sometimes to the point where I can’t breathe and I feel ill.

I frequently see existing items move out of the corner of my eye, then when I look, they’re completely still. 

I sometimes see bugs on my wall, bed, arms, etc., but when I turn to see them, they disappear.

I can’t recognize myself, and the only way I know that it’s me in photos and the mirror is because I remember what I look like.

I don’t feel like there’s anything inside of me. I feel like everybody has a personality, or just something inside of them (not physically), but I don’t. I feel like I’m hallow in a sense?

When things upset me, I have an urge to isolate myself and will go days without speaking. Another thing I’ll do in that state is destroy things, such as my favorite shirt, or destroy a friendship.

Sometimes I’ll feel like I have all of the energy in the world, like I need to go run for hours to get all of the energy out. It’ll feel like I’m floating in a sense? Not physically floating, but mentally. It’s hard to describe. My thoughts will be racing with random scenarios, and thinking about the future, but just a few hours, the next day, or a couple days later, I’ll be extremely depressive again.

My opinions on certain things will drastically change. Sometimes I’ll feel like I absolutely hate everything, and other times I absolutely love everything. I rarely just feel somewhere between those two.

I get extremely strong attachments to just about anybody who is decently nice to me.

There’s many more “concerns”, but those are just a handful off of the top of my head. I know those are very, very randomly listed things, but are any of them actual concerns or just something to ignore?
