Don't ever give up! I lived with my stuttering from age 4-5 until I became fully fluent at age 70. Mine was caused by my anger and resentment from an abusive childhood. Psychotherapy unlocked my speech. Though there are diverse causes for stuttering, both physical as well as emotional, there are also new modes of therapy. There's even now successful research into brain chemistry and the use of medication to treat stuttering. The disability is finally being seriously investigated and novel approaches are being found. Don't give up hope, keep doing everything you can until you find your solution. Best of luck, Sue
