The first rule in medicine is supposed to be Primum Non Nocere - First Do No Harm. I had years and years and years of speech therapy and it harmed me tremendously. I did not get any better and I thought there was something wrong with me. I thought I was mentally ill because I stuttered so badly. The speech therapy was harmful. Very harmful. Also there is no reason for years and years of speech therapy or thinking that I only need to find a better therapist. If the therapy does not improve after 1 year just drop it. The real sign of mental illness is doing the same thing over and over and over and expecting different results. It won't happen. If you don't improve after 1 year you are crazy to continue with it. The only ones who benefit are the useless SLPs (Speech Language Proctologists) By the way after having years and years and years of useless speech therapy my life improved drastically with the Edinburgh Masker and DAF speech prostheses.
