You have the rest of your life ahead of you and who you become now will eventually add up from years to come. I always felt this way too that maybe I shouldn't bother meeting new people, go on dates or look for a job that won't require me to speak but now I've met wonderful new friends and I'm employed as a librarian so I have to answer phone calls and help people at the self help desk. People must've noticed my stutter but I force myself to still finish my sentences and my speech therapist would tell me not to make other people's problems be my problems as they should learn to adapt rather than us changing ourselves to be a flawless fluent speaker. The secret was acceptance and disclosure - to let people and interviewers know in advance I stutter but to please ignore when I stutter and show me patience and empathy which shouldn't be too difficult to offer as the bare minimum as a listener. Last month I went to a stutter support group and it saddened me how much low self esteem the others had when I felt they were heavily overthinking and had nothing to be self conscious about in the way they talk. Take small steps at a time. I really think it's worth you look into a nice speech therapist. They won't fix or cure your stutter, there'll be some techniques here and there they can offer you, but their main objective is to change your mindset to not let your stutter ever hold you back. It's nothing to be ashamed about (easier said than done). Everybody has their own insecurities and flaws which is hard to notice. The right people won't care and will still show you patience. You have one life to live and you owe it to yourself to make the best out of your youth! It will be tough but with practice, things will become easier!
