It’s so hard living life this way

I feel so depressed right now it’s often hard to be around people because I feel like they are constantly judging how I say or do something or think that I’m annoying or simply don’t like me or want me around it’s so hard living like this it’s hard going to my classes at times when I get like this because I feel like someone is going to judge me by how I’m doing or saying something. I also get irritated very easily and it’s very draining sometimes I feel really content then other times I’m really depressed or easily irritated with everything and angry idk what to do sometimes I just wish I could shut my brain off!
