Yes I do! I feel much more open/relaxed after speaking up in a meeting, it's like the pressure is off and can feel more normal. But it wears off quickly and then it's back to the usual. I don't know how to create those emotions regularly.
That I don't know exactly. Anything that requires interaction with people makes me want to avoid it even if I actually want/need it. It's possible something in my childhood affected me but I don't know what (no one in my family is like me)
