How do you deal with having a stutter in this world?

How do you deal with having a stutter in this world? I just...i get overwhelmed sometimes. A lot of the times. I hate having to introduce myself to people, I hate how fucking rude people can be, I hate how people laugh at me and mock me and look at me like I’m a freak. I wrote an essay that was selected for this special event at my university and I was supposed to do a presentation on my writing and read from part of my essay and I couldn’t do it. Like I literally just didn’t even fucking go. I didn’t believe in myself and I didn’t want to humiliate myself again. It doesn’t matter how often I practice for a presentation. Once I’m actually presenting, the stutter won’t stop. And no matter how often I try to explain this to my parents or my girlfriend (I sometimes fear that the only reason she’s dating me is because we met on social media before meeting in person so she didn’t realize I had a stutter right away), they just don’t get it. I question if I’m capable of any job outside of being a reclusive writer. There are so many things I wanna do that I fear I can’t do because of my stutter. And there’s no sense in even getting into the big dreams because more than anything I wish I didn’t have to be so scared of just fucking talking to people, of presenting, of saying my fucking name. It’s like, what the fuck am I even doing here?
