2cool, I can’t speak about anxiety, but I can say that in generally, labeling oneself is in general very damaging.
One should never call oneself stupid, ugly, or mentally ill. Even thinking it, i.e., self-talk.
Especially since you say that this makes you “freak out.”
Can you try to focus on your wonderful qualities that I’m sure Hashem gave you? In fact, I’d love to hear all about them, & I’m sure I’m not the only one.
