I hate that I can’t speak normally around people

I hate that I can’t speak normally around people I can speak completely normally when I’m talking to myself, but when I try to talk to other people, I stutter or sometimes It feels like I’m choking on my words and they just won’t come out — almost like an anxiety attack. I’ve dealt with this for as long as I can remember (I’m 18 now). The more comfortable I am with someone, the better my speech gets, but it’s still not perfect. Some days or even months are much worse than others, and then sometimes I’ll have days/months where I can speak confidently without much trouble. I really want to speak fluently and feel normal in conversations. Has anyone else experienced this, and what helped you improve? I dont like how my friends react to the way I stammer or struggle to complete a word. It makes me feel even more self-conscious and frustrated.
