I get it , you don't want to be a burden ,which is a reasonable feeling, but isolating yourself? You're only gonna make it way worse than it is , cuz I've been through this , and I've isolated myself and oh boy it became way worse , sure you'll feel comfortable, But after spending lot of time isolated you'll want to break from the isolation itself,trust me isolation is not good , sure it makes you review a lot of things in your life,maybe even change the way you think bout things , but you'll want to get out of it. My advise (which I'm following right now ) is to do things that boost your confidence like making more money , be in shape , read books , and anything boosts your confidence, I am quarter but not half way there and I'm already feeling better and my stuttering reduced , not erased but reduced , A lot of people who stutter won't like this, but you gotta suffer in order to make things better , I know i wrote more than I should , but I hope it helps
