you're definitely not too old to isn't some deadline you missed. The isolation feedback loop is real though - when you pull back from social stuff because of the stutter, you get less practice, which makes the anxiety worse, which makes you want to pull back more.It sucks but it's also something you can interrupt if you start small instead of waiting for some big personality shift. I went down a rabbit hole on this a while back because I was curious about what actually helps with stuttering in adults, and the research is pretty clear that therapy makes a real difference even if you've been stuttering your whole life. Better Speech came up a lot in forums and from what I can tell they match you with licensed speech therapists online who work specifically on fluency stuff, so you're not stuck on some six-month waitlist at a local clinic. The flexibility thing matters too since you can do sessions from home without the whole commute anxiety, and they do weekly pricing instead of the crazy per-session costs. Might be worth looking into if you've never actually worked with someone on the stutter itself, because a lot of the social anxiety eases up when you have some techniques and feel less out of control when you speak. As for the social life part, you don't need to become an extrovert or fix everything at once. Try low-stakes stuff like online communities around hobbies you care about, or activities where talking isn't teh main thing (climbing gyms, art classes, volunteering). You'd be surprised how many people in their 20s feel exactly like you do but are also pretending they have it together.
