For now, please focus on next week and get better as soon as possible. This isn't worth the stress, you have people who depend on you in much more profound ways.

Sorry for wishing you ill, that was not okay.

I don't hold grudges in general, but I learned in many hours of therapy to expect more from a friend. Telling me it's my own fault that someone goes on a vendetta against me just because you support their cause is definitely not it.
