Forgetful Friend

I have had my senior party planned for weeks. It was pretty important to me because it was basically the last time my friends and I would get to hang out before graduation and the subsequent scattering of people. My friend was invited to this, I reminded her, and she DID NOT SHOW UP. She “forgot” like she constantly does, and she scheduled work on top of it (as usual). Does she even want to be my friend? Is this just part of her mental health struggle? I’m kind of at my wit’s end—we’re supposed to take a trip together soon. I don’t want her to feel forced to go with me to that if she doesn’t want to, yet I also don’t want to exclude her if this is her mental illness.

I know I’m probably being over-dramatic or it’s probably a communication issue. I just needed to vent.
