Has anybody else gone from overt to covert?

Has anybody else gone from overt to covert? In the past year or so, I have really improved a lot. Before, I used to really struggle in basically any interaction and would often get absurdly long blocks. I don’t even know what changed, aside from being forced to talk to other people. Now, however, I feel like I have gone from knowing what I want to say but being stuck and stammering to not even being able to think of what I want to say. i think I stammer less because I am not ever saying what I want to but it’s like I can’t even formulate what I wanted to say in my mind first. I think I might just be circumventing anything that would have made me stammer before without consciously choosing to do that but I am not sure. To be honest, feeling this inarticulate and absent minded during conversations is just as depressing as obviously stammering. I am just not really sure of what has happened nor what I can do to fix it.
