You're strong and brave. You'll get through this as we did. You're articulate. Honestly, it doesn't get easier; we're here for you! I used to skip the first day of college courses to skip the obligatory stand up introductions. I wish I hadn't. We are who we are. If others are stupid enough to want to mock how you speak, so be it. One less person to consider being a pall with. Thier loss. You will achieve your goals. Don't ever let stuttering impede on them.
