From someone with a severe stutter, DONT let people dictate how you feel. You can only control variables you can control, so if you don't want to feel like crap, tell yourself "I don't want to feel like this. I don't care about what she says. She doesn't matter to MY life." Soon your brain will understand and you'll just stop caring. It's good to have a support group and people you can rely on for you won't feel as lonely. Hang in there!
