I feel like my ability to effectively communicate is worsening day by day and I'm becoming Anti-Social, I don't feel like talking in front of strangers. Will speech therapy help? Stutter was moderate to severe on some days before I was 18 year old, now it has become severe on most days and moderate rarely, I don't know what to do. It's out of my hands I feel like, even if I accept it I don't want to be like this forever.
