Severe stutter, getting worse with age. Looking for real improvement — medication experiences?

Severe stutter, getting worse with age. Looking for real improvement — medication experiences? Hey everyone. I’ve been reading this community for a while and finally decided to post. I have a really severe stutter and I’m tired of living around it. Natural techniques (speaking slowly, breathing, reading out loud, staying calm) have helped some people here, but they haven’t worked for me. My stutter gets stuck on multiple letters in a word for example, a sentence like “I have a doctor’s appointment” can come out like “I h-h-hav-e a d-d-oct-ters a-p-p-pointm-m-ment” and that short sentence can take me 15 seconds. While I’m saying things my hands sweat, my heart races, and I overthink trying to be fluent which only makes it worse. It’s gotten worse as I’ve gotten older. I think part of it is that I was very quiet as a kid and didn’t speak much, so I’ve always been the “quiet” one in family/friends/school. I hid it by not talking or avoided using trigger words. Now I barely talk to my family because it feels too exhausting and embarrassing. I just want out of this mess, even any improvement would be amazing. I’ve read posts where people say medication was the only thing that helped them long term or even permanently. I’m curious about that. If you’ve tried medication or been prescribed something, did it actually help? How did you start the process? Any side effects or things to watch out for? And for people who tried therapy + meds, did combining them make a difference? I’d really appreciate real experiences, recommendations for what type of medications are effective. I'm desperate for anything. Thanks for reading.
