My mom doesn't care about my allergist reaction?

Yesterday I broke out into hives from my new meds. I took benyrdtl and It made me dizzy. My throat has been itchy and today I told her it was itchy and told me to stop badgering her and take a bebyldrl I told her it made me dizzy she said to shut up an then she hit me in the head. My dad came home and then canceled my phone. I think it's ridicoulas my throat is still itchy red and it can close up. I was thinking about taking the meds I'm allergist to before school tmrw so then if something happens to me like my throat closes I will have to go to the er then the school will call my mom and that'd make her feel really guilty and to start listening to me.
