Hey! Yeah that happens to me too a lot. Luckily the next day I usually just forget about it. So if I’m ever ruminating about a word I tell myself that I’ll probably forget about it tomorrow and that helps. Btw though I’m also on sleeping meds though so no matter how anxious I’m feeling about stuttering on a word I can still fall asleep no problem at night. So it might not work if you’re finding it difficult to fall asleep at night.
