Am i wrong for feeling dejected about this?

Ok, so Sunday i broke and dislocated my ankle playing ice hockey. I'm 18 yrs old, home schooled, i live at home with my parents 15 yr old brother and dog, and almost done with high school. I will probably need surgery to put in pins to hold the bones back together, i'll know more tomorrow when i get to see the orthopedic surgeon. So anyways, the day after i broke my ankle, my mom was already enrolled in a 2 week long exercise cl, that runs every week day, for about 8 hrs a day, and it's a 45 min drive from our house. While i was laying in the ER, high on pain meds, waiting for the doctor to come and set my ankle and put it in a cast, my mom was trying to find ways that she could still go to her cl, even the next day. Even after the nurse had told her that i would for sure need someone around to help me move around the house, etc. I didn't say anything, but that really did hurt my feelings, and made me feel pretty worthless. So the next day she left me at home around 8 am, and came home at lunch time, but made sure to mention that she would be late in getting back to her cl because she came home....so i don't know why she even bothered. The next day she didn't come home at lunch. My dad gets home at 1 pm, but he's usually not in a good mood after work, and all he does when he comes home is treat me like some pathetic invalid, which doesn't do any good. My brother has been taking good care of me, getting me whatever i need and letting me watch tv when i want to, and my dog is here to keep my company....but i still feel dejected that my mom has been so insensitive and eager to just get away. And it ran all over me last night, that after she'd be gone all day long, she got all over me for not keeping my foot elevated and iced. I mean, she wasn't here all day long, and then she comes home and yells at me for that? So anyways, should i just get over this, or do you think i have a point in feeling kinda sad and dejected?
