Anyone’s stutter worsen when they’re tired/stressed etc?

Anyone’s stutter worsen when they’re tired/stressed etc? When I’m feeling a bit negative, my stutter is so much worse and I struggle to get a sentence out. Then I feel negative that I can’t speak and it’s such a vicious cycle. Ugh I’m literally writing this as I’m sat with my friends and have held back speaking twice because my stutter is just awful today because I’m stressed. It’s so annoying! Normally I just wait for it to pass. Ugh. Any advice?
