Appreciation for Seizure Medication

so I'm not sure if any of ya'll are going to agree with this but my dad wants me to thank him every time he buys my seizure medication so I told him off say "that I don't really have to thank him". Now don't get me wrong I do appreciate him buying my medication I'm not trying to be unappreciative but I just feel like thanking him for the one of the things I hate most in the world is like thanking god for my epilepsy. My parents are always immature assholes anyways always treating me like everything my fault, treating me like a I'm a burden and just one big problem, Like I was the one who asked to be born in the first place. it's times like this when I truly remember why I became so dead and cold because no one but people who are just like me can truly understand what I'm talking about
