Looking for advice for the next step to improve myself (social anxiety, stuttering, etc)

Looking for advice for the next step to improve myself (social anxiety, stuttering, etc) I'm in my late 20s, have a stutter, have social anxiety, and I'm suffering from lack of friends. I've been successful in my career and, as a result, I'm pretty confident at work and don't have too much trouble speaking at work. I do have trouble meeting people on a social level and as I've grown apart from my friends from my early 20s, I'm finding myself lacking for friends. What I need advice on is whether to tackle my stutter, social anxiety, both, or something else entirely. A few years ago, I asked this question to a stuttering group and a social anxiety group. Both groups gave me the advice to go the stuttering group's meet up. I went to three meetings over the course of a few months and had a pretty horrible experience. My stuttering in those meetings was the worst it had been in years and I left those meetings feeling like a broken person. This leaves me thinking that I should probably work more on the social anxiety and social skill issues that I have, but I wonder if I should do something different since I have a stutter. Any advice is appreciated. Thanks :)
