I struggle with speaking

I have social anxiety so I don't say much most of the time but something I've noticed is I struggle with speaking. When I do talk I have a hard time saying what I'm trying to say. I usually need to talk really slow and think about what I'm saying. I was just wondering if anyone else here struggles with something similar or if there is something else wrong with me. I've always connected it with social anxiety and isolation but now that it's getting worse I'm not so sure.
