I can't believe my mother did this on X-mas..

I had my last of 16 chemo treatments on 12/16. For some reason this one hit me harder then the others. I was fatigued, nauseated, and vomiting. So on Christmas Day I was still feeling terrible. But here is what is bothering me. My mother lives around the corner from me. She wanted me to come over to her house on Christmas. So,she called me on Christmas Eve to tell me to come over the next day. I told her I was not feeling well, I was not able to keep anything down and I was still very tired.I told her it would be best if her and my dad come over to my house. I told her they could bring over the food they cooked like they did when I was feeling bad for Thanksgiving. Well, she told me she didn't feel like doing all that because it was to much trouble to pack up the food.I repeatedly told her I was not feeling well and that it would be best for me. She told me I am not the only person feeling bad this Christmas and that I need to come over to her house because she was not coming over to mine. She was like I had breast cancer to and I still did things.I told her that I was not feeling well and that she could stop over anytime. She then said well "we are not coming."So after all that she did not come to my house..she sent my dad over with the gifts and some food. She did not come at all. I talked to her not to long after my dad left, I asked why did she not come with him..she said she was to emotional at the time. She said I was trying to avoid coming to her house..I told her I told you I was not feeling well and you just ignored me..I told her I expected her to just say ok I'll come over but you just ignored me as if I were lying..she said if I am trying to make her feel bad about what she did she said she's never going to feel bad about it...so I am not talking to her. I am just pissed and disappointed.
