It makes sense you wouldn’t visit her while dealing with all that! Illness takes so much out of us (on top of time to heal, overwhelming emotions to deal with, need to be safe, less $ available and PTO, etc.) Some young people really don’t understand this (in my experience as being someone who has health issues while I was young).

You should talk to her about how you went out there and A. the making out with her bf/not giving you dedicated time and B. how she didn’t help with the boundary you set of him not hugging you etc!

She hasn’t taken your illness seriously at any turn it seems.
