You are more than your stutter. You are important. You are loved. You are not alone. I feel with you. Many of us block on our name. Try talking with your boss or HR. Fuck it and be open and honest about what's happening. Maybe they can slide you into a different role or design a script so you can practice. Practicing always helps me. Even if I'm blocked, knowing what I'm going to say brings some shred of solace. You have to reach out and connect with someone. I know stuttering makes that hard for us but don't wall yourself off. There are good people out there, patient people who care. You have to find those people and lean on them for support. Everyone needs support, regardless of their capacity or diability. It's going to be ok.
