Be realistic. What are your options? Don’t speak, feel shit and socially anxious? Or feel shit because you spoke and had a severe block ? I mean you are going to feel shit either way. But the second option might or might not help you in the long run with the anxiety even if you block for minutes. It needs a lot of courage and perseverance. And you have to curb your expectations. Speaking fluently is not the goal. Managing your emotions afterwards and the judgments about yourself is the goal. Forget what others think. it might be extremely uncomfortable in the moment but that is something that we have to manage. I have a severe stutter and I will not allow anyone to say I don’t without meeting me. I have blocks that feel like deep, bottomless pits where I can not get out of. I still did some teaching this year at my university. I couldn’t sleep every week before the session and I mostly wrote on the blackboard, not talking much. But, at my own pace, I said more and more during the sessions. This really helped me mentally. It is easier for me now to go the the bakery and order some bread or visit the ice creamery and order a scoop of ice cream. All because I had some good experiences. Most people don’t care that deep about your stutter. Even if you block for ages. You care. And that is in your control.
