Don't give up. Stutter is very much psychological, so the more you lean into the negative thoughts the worse it'll get. It's a feedback loop. I know it's hard, really hard at times, but keep fighting. It might be a silly suggestion, but if I were you and I was surrounded by family who made me feel worse, I would move someone very new and start a new life. Regardless of what you'll do, keep being active on this sub/r. We're all in the same boat here
