I like the idea of sending a nice gift if you don’t go. That shows her that you do care about her. Hopefully, she won’t hold any resentment that you ‘got sick’ and didn’t attend.
Are you just talking yourself out of going due to your own anxiety? Is this something you would like to combat and learn to conquer by going?
I really don’t do guilt. Lots of folks have tried to guilt me. I’m not having it.
