Hey its not because you suck or because of the stutter. Its because someone else showed more cleavage. All kidding aside. You are not worthless and ya dont suck. Your stutter doesnt define your worth. I have had so many interviews that i thought i screwed up because of the stuttering. It was never for that reason. Someone else was more suited for the job. You are an amazing person and so strong!!! Maybe a tip i always do before i have an interview or when i meet someone new. I tell them i stutter and that its something physical that you are born with it like haircolor or color of eyes. If they ask more ya can also tell them that emotions make it worse but arent the origin of it so slowing down or calming down doesnt make it go away. I also tell them how they can handle it. Listen to me and keep eye contact. Dont finish my sentences and focus on what i am saying. Keep your head up. Not our fault we got it and we wont let it control us!!!!!
