I’m done with my parents

I’m currently sitting here drinking a hot medicated drink for the third time today because I’m making an effort on trying to feel better. I’m constantly sneezing, my nose is running and I switch from hot to cold and then cold to hot 24/7. I’ve been like this since Thursday night. I’m currently having tonsillitis for the 20th time since last November and it has just reappeared sightly. I feel no different to what I did on Thursday and yeah, I have school tomorrow. I’m willing to go in but my parents think that I’m putting it all on so I don’t have to go in tomorrow. They fully well know that I have my favourite subjects tomorrow so why would I be trying to skip school?! I feel like utter shit rn but they can’t see it. I’m making an effort. I HATE taking medication so if I was faking it, would I really be taking it? NO.... FUCK NO.

How to I get my parents to understand me?
