Almost normal speech adult going back to stuttering when upset

Almost normal speech adult going back to stuttering when upset I used to stutter quite bad as a kid, it improved so much as soon as I left home at 18, I think it was caused by having some trauma at home. My accent changed too when I moved out and I think it was a way of subconsciously helping with the stutter. anyway, I still stutter badly if I get upset and emotional. It makes it really hard to resolve arguments with my boyfriend because I feel like I'm unable to get any words out, it feels like when I'm really upset I just go back to being a little girl with no voice. I was wondering if anyone else had a similar experience and if so, do you have any tips on how to speak normally when the stutter gets triggered. It makes me feel so vulnerable when people hear my stutter because I feel like they can see all my trauma
