I am really sorry to hear that. That must be really tough at times and I feel it. Some days it is really difficult for me to the point where it makes me feel like I can't talk at all. I have to push through it but sometimes it really gets to me mentally but I try to make it not. I'll have good days which I won't block and speak with almost 100% fluency then the next I will get very down on myself. Even though it has just recently become a bigger problem for me and I know how hard it can be.
