I not sure if I’m considered Adult Onset because I stuttered as a kid for a year, then again in 4th grade for a few months. Then it happened again a few years ago when I was 21 and it lasted 3 years. I went to speech therapy twice, and of those 2 times, my therapist didn’t think that I have a stutter. This is because whenever I feel safe and confident, I stutter wayyyyy less. My “personal” belief is that my stuttering is caused by anxiety and low confidence. I was in a deep depression for 3 years when I had my stutter, I got kicked out of my university because I was so beaten down that I didn’t even show up for any of my classes because I was afraid of talking to other students due to my stutter. However, I went to a party and did MDMA and met a guy, who is now my boyfriend. I was so confident when I was on it, and that confidence carried to my normal life. After that day of doing MDMA, my stutter improved dramatically and within a couple of months, it wasn’t even an issue for me. I now still stutter once in a while, but it’s not to the point where I don’t wanna leave the house. I love making new friends and socialize now. I cannot stand spending time alone anymore because I love talking. I talk so much now because of my fluency that sometimes other people think I’m annoying because I wont shut up. I really really think it’s all about being confident and not think about your stutter. I know it’s really hard not to think about it because it’s holding you back from your social life, but practice to direct your attention elsewhere. I hope this helps.
