Stuttering does make it very hard to make friends. 3 years back my stutter was so bad I could hardly say a single word. I've always been nice and polite but no one wanted to talk to me. But eventually I did still make some great friends. I know Stuttering is hard and most people will never know how we feel but domt loose hope. My friend that I made when my stutter was at its worst recently told me that I hardly even stutter anymore. I tried so many things to help like speach therapy, reading books out loud, practicing saying words to myself. But the most thing that helped me was putting myself into situations that, as a guy with a stutter, I was afraid of. I've always been afraid of new things and now that I've put myself into so many situations were I need to speak or has helped me a lot. I pretty much did a presentation to my higher ups at work to attempt to earn a promotion. I did very good and spoke very well. And i had been afraid of doing that for like 2 years. Maybe some people will never be able to improve their speach very much but I would try speach therapy, reading out loud, and putting yourself in situations that make you uncomfortable.
