“Just spit it out”

“Just spit it out” This is the most insulting thing I’ve ever heard, from my own family, no less. I’m in my late 30s and just started struggling with getting words out. By the time I can regain my composure, someone already dropped this gem, and I forgot what I was talking about anyway. Often times, I feel like the stress in my life caused this stutter, but the stutter just adds to the stress. So I find myself trying not to talk much. At least my coworkers get it. Just wanted to rant.
