Being 3 years older I perfectly share your feelings, I'm not saying that stuttering completely ruins your life but we must be honest and admit that it is an important conditioner, that it requires so much work something that should be as simple as it is to communicate is frustrating, really frustrating. Whenever I have to do something in my life always goes through my head the same thing "this would be much easier if I didn't stutter" luckily I always try to be positive and move forward, what definitely puts everything downhill is that there is no solution, at least not a definitive one, I would prefer a thousand times to suffer something worse but at least that problem has a fucking solution, no matter how much effort it requires. Personally my way of not going crazy and totally sinking is that I can use the time I would normally spend socializing to do things that make me develop personally (socializing is a fundamental and necessary part of life but at the end of the day most of the time it is "technically" a waste of time). That's what I can tell you my friend, without trying to fall into cheap consolations that definitely won't help you.
