I had a lisp in elementary school. I went to speech therapy. I'm not sure if it was fixed. When I say a word that has an s in it. Sounds like a hiss?

Evaluate ; re-focus. Consider getting a professional evaluation of your speech first. Most likely you are focused on a problem that no longer exists or is miniscule. Friends or a therapist can help you to broaden your focus and find other ways to measure self-worth. A family member went through something similar and she is fine. Peace and good health!
