So this probably isn’t what you want to hear but it’s what you need to hear, I needed to hear it when I was younger. You said that your stutter is “sabotaging your social life.” it is, but only because you’re ALLOWING it to sabotage your social life. Once you come to terms with your stutter and accept it and stutter openly without caring what people think it gets way better. It can be hard to get there but that’s what you gotta work towards. I’m there now and my life is 100 times better, I’ve been stuttering all my life and ever since I gained that confidence I didn’t care at all what people think of my stutter or me in general. What helped my was my music, I listen to rock music (metalcore/heavy metal) and it gave me that “don’t give a fuck” mentality and I’ve never been happier. It’s all about your mindset, 1) gain the confidence 2) hang out/ ask out the girl 3) go from there
