Everyone has some "defect" whether big or small. Stuttering doesn't make someone unlikeable, and in the adult work people USUALLY don't care whether you stutter or not. It's nearly impossible not to worry about your stutter, hell I do all the time. One think I will advise you to do, is go out and do all those things you love / want to do. As nerve racking as it may be at first, that's the first step in my opinion. Just do what YOU want to do, and don't let your stutter stop you.
