Mind going blank follow up

As you suggested, I will I did a model with embarrassed in the feeling line-

C in a conversation
T I don’t know what to say. I’m so stupid.
F embarrassed
A stop talking
R conversation dies. I am not connecting with others the way I would like.

Here’s another one I often feel

C saying words in a conversation
T what I just said doesn’t even make sense to me
F embarrassed
A feel insecure. Avoid putting myself out there
R be overly critical of myself as I’m talking and after a conversation

Where do I go from here?
