Talking is hard

Why is talking so hard for me? It's like I can form sentences in my head but they never come out the way I want them to. Or sometimes I can never form the sentences & I'm left speechless. I know I should talk more. It might make life a lot easier. But I just don't know how. Maybe when I was a baby I accidentally skipped a lesson in learning how to communicate. My quietness has led to much loneliness & being invisible in a room full of people. I low-key wish I was more of an extrovert & could talk the paint off the walls. Just another aspect about myself that I hate.
