I just wanted some help because I actually don't know if I have anxiety or not and whenever I look up what I'm feeling there's nothing much there that relates so just wanted some help.

I'm 18 now but from age 16 and before I never really had a problem interacting with people or never really noticed being weird in social situations. Nowadays, whenever im like walking on the same side of the road as someone or if someone is walking toward me, I always steer clear or pull out my phone etc, but ALWAYS avoid them no matter who it is. Im scared of answering the phone too, but im not scared to go out and do social stuff with my friends, like out to a club or something? Im really confused, and sorry if I sound like an idiot for posting this I just wanted to get it off my chest
