I am so exhausted

I'm 14 (m) and I can never be happy, if I'm nervous or down right panicking about anything once I fix the issue my brain cannot stay happy, it has to move onto the next thing to worry about, most times its my body or how people look at me, everyone thinks I'm just shy but no one knows how much I struggle and I just wish I could get some support from the people close to me but no one would care. There's so much going on in my life right now I just don't know what to do anymore, I wish I had someone to talk to, I wish I didn't feel like this all the time. I just wanna be normal like everyone else because everyone I know thinks anxiety is weird but its just my life.
