I used to really enjoy hanging out with people and making new friends. I still enjoy all the same hobbies if I can do them from home by myself, and I really want to make new friends and have fun but I can’t seem to. I went to a concert a while back and I couldn’t even bring myself to jump and have fun, I just froze and stood there. I’m nervous about being around people now since I don’t ever know what to say and it gets kinda awkward after the initial subject ends. I feel like I’m afraid to let loose and have fun, I won’t even drink anymore because the thought of losing control terrifies me. Is this social anxiety or something else??
