Am I overreacting?

I was in the hospital with intense pain in my lower abdomen/lower back and I was scared because I had never felt this type of intense pain in my entire life so the first thing I did was call my mom because I was sleeping over a friend’s hour and didn’t want to ruin my friend’s birthday party. I started panicking asking her if she could come get me because I was petrified about this pain and I couldn’t really get up from the floor. She tells me she hasn’t showered or combed her hair and tells me to take an Uber and when she’s done she will meet me there. I got upset and told her to come get me now and she sighed and said fine. We get to the hospital and I’m doubled over in pain sitting in the waiting room and she then starts complaining how she didn’t have time to comb her hair and that she had so many plans for the day and that she’s stuck at the hospital with me. I looked at her angry and ready to cry and started to tell her off when my dad butts in and says she’s right that she did have plans but I should be grateful she came to get me. I was about to tell them both off when they called my name and I went back. When we got back there, I asked her if she felt bad saying that to me and she said no so I told her she can leave and she said no because she’ll feel bad.

I was there for 7 hours and had tons of tests run on me and was completely exhausted and she said she didn’t feel like driving home so we were now stuck at my aunt’s for the night. I ask can we please go home and I get yelled at once again for being inconsiderate of how tired my mom is. Days later, I bring up what she said at the hospital when I’m feeling better can discuss this in a healthy manner and i had asked her how would she have felt bad if she had left but not felt bad basically guilt tripping me into making me feel like I’m burdening her day? She made me feel like crap ON TOP of the fact that I already felt like crap. She still has not spoken to me since I called her out. Sorry that was long.
