In that case, I feel that if you were to go to a doctor they would be aware of this. They may tell your mother you dont need it. I also would advise you to begin trying to detach from your mother a little bit. The more you rely on her for help the more she will feel like she has total control over you. I know it's scary, but once you gain a feeling of Independence you will begin to feel much more powerful! Don't worry about curing your stutter just yet. Focus on becoming OK with yourself and who you are. Try to make other around you understand who you are. Fluid speech comes gradually, but you must brush away negativity in your life first. LOVE YOURSELF!
