I've been there. I have a pretty severe stutter and a lot of secondaries but I'm still pushing through. I've isolated myself my for years and been through what felt like hell. Honestly, the stutter is never going to go away, that's something you need to accept to be able to feel better about it. It's like AA, you have to admit it to yourself before you can start working on it. I have a long way to go but I no longer care if I stutter in front of people. I live my life as best I can and try to ignore the thoughts of what people think. It's mostly in head. Most people honestly don't care and are willing to be patient with you if you give them a chance. There are always going to be assholes are stuttering or not. You just need to put yourself out there more and live your life. Be selfish about your life and make yourself happy. That's the point of this life. There's no point in letting it go to waste. I wish you the best buddy.
