Sorry to hear that you are struggling like this - I have a stutter as well, and it definitely makes things difficult. I feel that career-wise I am limited because I can't speak well in front of others (sales, meetings, pitches, etc) and makes it incredibly hard to do well in interview. My stutter is significantly worse when nervous aka interviews. Hang in there though, there are plenty of well-paid jobs that do not revolve around constant talking. Make connections with people in your circles that can help recommend you for positions and such to help push you past the interview phase. There is so much more to life than you job, and you have value outside of your voice.
