I'm sorry you feel that way, I feel very depressed some days about it but I can still get a job, go traveling, buy a house, have children, get old, make money, eat nice food, see nice things! You've got to think about the bigger picture, yes a lot of things are more challenging and it is unfair having a stutter, but hey life is hard and life is unfair and if you can't accept that, well, you're gonna lead a pretty depressing life aren't you! I would suggest seeing someone, talking about it, speech therapy, meeting other people who stutter, relaxation techniques, look at ways to get in a better mind set! Think about things you have achieved rather than things you haven't, and build on that positivity!
