I had 103 fever and my sister and dad had 102. Mom took care of them not me why?

My sister almost recovered and dad and I fell sick at the same time. Though I had more fever than them. I kept calling them from my room. My mom answered from afar and didn't show up. And my sister and brother completely ignored me. After 15 mins when I got angry. My mom said." I'm tired of taking care of you" though exactly after 15 minutes she took my dad to see a doctor and didn't even bother to see me how I was doing after that. Why would she do that to me
