Dude calm down. I use to feel the same way. My stutter is so severe when it gets out of hand that i can not even say a word. Im 31, have 3 babies, a beatiful wife, master degree, a decent job and a business of my own. By 21 i was still a virgin, jobless, i drop out of school, etc. Two things helped me: 1. Never stop doing what you enjoy doing. That will help you when you feel down. 2. Get yourself into "more important things". For example, i cannot lock my self in the closet and cry because i stutter, i have babies to feed and a job to atend, a wife to please, etc. This second thing helped to concentrate into another things instead of thinking only in my stutter issue. Do you know how i got my first girlfriend? I enjoy a lot boxing, i met a girl in a gym, made her my girlfriend and married her. I found that girl doing what i enjoy doing. Dont forget point number 1. Good look friend!!
