I feel you, I have stutter blocks as well. It's so tiring. I made the same post here too back on my first day at college, it was on my 2nd account. My stutter bothers me a lot in my studies and I struggle in my everyday speech, I couldn't stop worrying about it. I'm third year now my stutter still hasn't gone away but I just getting used to it. Tho I still struggle to speak because of blocks it has reduced to the point it doesn’t bother me as hard before as it used to, without any therapy. Maybe try to chill, it's not the best way for now but maybe in the future, you could manage your stutter a little bit. Try to expose yourself in conversation don't hide but don't push yourself too much.
