Ah man, I'm sorry. But the fact you're still going is good. I wish you luck in life. I don't have an issue with anxiety, and I can read fluently, so I just leave it there. It gets wildly embarrassing though, I understand you. Mine doesn't have much of a pattern other than becoming more clear if I'm experiencing any strong emotion (good or bad, & sometimes I legitimately can't get words out right) or the environment is a bit loud. I guess it doesn't impede me much, so it's just been there.
