Feel lost. Inclined to believe the root cause of my failures is my stammering. I (27m) feel like a failure. I blame a lot of it on my stammer. It hinders everything....it's probably the worst thing one can have. No one seems to think of it as a disability, it's crazy! Anyway. Im a graduated internation student who is looking for jobs and I can't get myself to give interviews. I know I'm going to stammer like crazy and put everyone at the panel in an uncomfortable position. I don't even want a job. How am I going to sustain there ? It's not the work I'm worried about , it's the daily calls, meetings ,scrum ...why would I put myself through that? The constant stress..every new day starting in dread. I have a clock on my head( due to my international visa status). I don't see how I can overcome the biggest hurdle in my life. I know I am all over the place , but I had to share this somewhere, preferably to people who know what it feels like to stammer !
