How often do you use stuttering as an excuse to not do something?

How often do you use stuttering as an excuse to not do something? I've been doing this for as long as I can remember. I realize I do it constantly to literally just talk myself out of trying or doing anything new. I'm currently looking for a new job and the main thought in my head is about how it won't work out because I stutter and how I'm just setting myself up for failure in the long run. I worry I won't even get past the interview because of my stutter(especially if it's on the phone), but it's crazy how often I employ that kind of negative thinking. I can't go a week without applying that sort of thinking to future plans( going on vacation, getting a new apartment, asking a girl out, practicing my French with people, talking to friends in discord, etc), and you know what the worst part of all this is? When I actually ignore the thought and go ahead with what I'm doing, it's not even as bad as I imagined it to be! I mean, it can definitely be bad, I will often stutter and my attempts to work past a block will be clumsy if successful, but it's *nowhere near as bad as I imagined it to be.* I always imagine it to have earthshattering consequences when that's almost never the case. And this has held me back my whole life. I've even put off going back to school because I'm worried that the teacher will ask us to do a presentation for an assignment. Why do we do this to ourselves? ​ I'll admit it, I hate that I stutter, but I hate this nagging, ever present voice of doubt in my head chipping away at my mental health *way, way more.* An infinitesimal amount more.
