I'm 25 right now and I absolutely recognize this feeling. Even though I have quite a lot of friends and I'm pretty confident about myself as a person, I sometimes get so frustrated and sad when a conversation does not go as I hoped. Especially talking to girls can be a complete nightmare. I sometimes feel like I'm never fully expressing myself and that the only thing people see is a filtered version of me. But whether I like it or not, my stutter has made me into the person I am today. I've always had the need to prove something, because I felt like people did not expect much from me. This has made me into a very hardworking person that will do anything to prove to myself and to others that I'm just as worthy and just as capable as anyone else. With this mentality I recently landed my dreamjob and I have made quite a lot of progress in the gym and with climbing :) . Stuttering sucks, but it's also a part of you and it makes you unique. I know it's easier said than done, but own your stutter and I can guarantee you that people will look at you in a completely different way. You'll be amazed at the things you can achieve when you don't see your stutter as a weakness, but rather as a challenge. I'm definitely not there yet, but this realisation definitely was a game changer for me, as corny and obvious as it may sound. hang in there bud, there's light at the end of the tunnel!
