I feel you, but as others have said, there's a good chance it does get better in your 20s. For me personally, it happened when I was 21. At that age, I did something kind of counterintuitive: I joined the radio broadcasting club of my university and tried to put myself out there as much as possible. Hosting radio shows, doing podcasts, all the things a stutterer shouldn't be able to do, I tried and I did it. My social environment was very understanding about my condition and gave me a feeling of safety and acceptance, nobody laughed when I had a block. It probably helped, that my stutter wasn't that severe, but I had these jaw-locking blocks during live-shows, so it was still pretty challenging. Over time, I grew my self-confidence and even lead the 40-ish editors as editor in chief for one year. My stutter steadily got less and less important as I had more important matters to worry about. This year, I'm going to finish my masters in media sciences and already got a job lined up starting in July. When doing interviews with companies, it helped me to frame my stutter as an advantage for me, like: Look at me, I've decided not to let my stutter define what I can and what I can't do, and instead take matters in my own hands. For potential employers, this can be a sign of strong willpower and dedication, and it's definitely a plus other candidates don't have. Out of the six interviews I had until now, I got five offers, so it seems to strike a chord - at least in my country (Germany). I hope my ramblings were of some use to you and I wish you all the best! :)
