My anxiety holds me back a lot, but i just convince myself that no one cares about my stutter. No one cares if i make mistakes, no one is truly focused on me and my speech. So i act like its nothing. I try to speak slow, clear. If i fuck up just shake it off. At least for me, its really a confidence thing. I can notice when im flowing or when im about to get stuck, so i just work around it. Again, its more of a self esteem thing. If i believe i can go out there and do my job proficiently, then a stutter wont stop me.
