Is not talking in high school really a big deal?

Well I was diagnosed with OCD, Generalized anxiety disorder, and Social anxiety. Im 17 years old and a guy. Im in grade 11. I was home schooled for awhile until coming back to public school now. Its not just my anxiety why I don't talk. I just don't want to kind of. Is it really such a big deal? I don't like when people think I'm weird for not talking. Plus if I DID talk, I would be too loud and I don't know. Not sure what kids MY AGE will think of me.

Also: If you have OCD, do you also have the mindset of like go big or go home? Because I know I do, like in living life in general.
