I'm no therapist nor anyone with much psychological knowledge but I have been in a similar situation when I was much younger, I was seconds away from trying to kill myself due to my stutter until I decided against not doing it. I know how the pain of stuttering is (and the people on this sub do too) but killing yourself isn't the answer. This may be terrible advice but what I did to when I felt that my life didn't matter is that I decided to just fuck it all and go out, talk to people, try my best to deal with my stutter. Sure it was horrible at the first, the embarrassment and pain of having people look at you confused and unable to understand you was hard at first but at that stage I stopped caring about what others thought of me because I stopped caring about myself. As fucked up as this sounds it eventually worked, I found myself building up some confidence (if you can call it that) and just not caring about what others thought of my stutter, eventually you'll find people who feel the same and will be able to see past the stutter too. I'm awful at wording this because like you my social skills are awful but I'm always trying to improve, because in the end, what do I have to lose? I can only go forward from this point
