I feel your pain. This sucks! A couple of thoughts: One day if you do the work, you can beat your stutter! I did, and I was where you were before. Second, this is more of a karma answer: there’s negative energy in what a “friend” of yours did to you (How can they be a friend if they mistreat you like this?) It took me a long time to learn this: even though you were wronged, holding on to that feeling will cause more pain than good for you. Again, I’m sorry this happened to you!
