Friend not committing

C: Friend states she can’t commit to girl’s night because she has had too many social functions recently. (Limited number of girls can attend).
T: I want answer now so I can invite someone else
F: anxious
A: not letting others have space to decide for self, hint to her that I’d invite someone else if she doesn’t commit, be impatient, not getting to plan
R: I worry about about not getting last spot filled

T: I’m not important enough to commit to
F: rejected
A: hate self, question my “fun-ness” not love myself, and not see my worth
R: perpetuate the thought I’m not important enough

I’ve created two thoughts about the circumstance. I’m realizing this is drama in my head but not sure where to go from here.
