One thing stuttering has done to me is humble me. The pain got too much one day and I cut all connections with everyone I had met except one friend I respected because I wanted to leave behind my past and start new as a more mature person. I dont care as much anymore about achieving the dreams I had when I was younger but instead I just want to find happiness. To do that I need to be the best version of myself both physically and mentally. Only I can save myself on the hardest moments of my life. I can only depend on myself. Having a loving family helps a lot not ending it. Living alone with no friends and having people party all around your house is the worst feeling. Making true friendships that lasted is something I never accomplised but I havent lost hope yet. The only advise I can give you about managing painful emotions such as rejection from people you can't socialize with is not to act on your feelings in front of them and if possible find a hobby to relieve your frustration such as lifting weights (the endorphin release in the brain is like the best emotional pain killer but you need to work hard). Having a strong looking body can at least make others (especially women) not think you are a sensitive, shy, introverted or weak person just because you dont talk much. I know I talked a lot about myself when this post is about you but I believe one of the best ways people get help is by reading a lot of experiences from others and finding the answears themselves.
