We all went thruogh that feelin bro. Its normal . But keep in mand how valuable you are and that you will get better and better. I have had a very severe stuttering and today I am better. I also thought that I would not be able to do anything in my life, and little by little I am achieving things. I still have a long way to go, but it's a little at a time. With perseverance and fluency shaping. You have to believe in yourself. Be strong!!
