<human>: Can you condense the text into three sentences or less?

(Mind me, english is not my first language, anyways) First of all i'm new to Reddit but this seems like a nice community, perfect when i have no one to talk with about this topic since i have lost friendships recently, but that's not what im making this post for.

What's this post about? (it'll be a bit long)

I'm almost 18 and my parents have been officially separated since i was 11 (they were separated before for a period of time before), and i never made too much out of it, to be honest i didn't care much about it. But it wasn't until my fair amount of health issues started worsening that they had to keep in contact. I have allergies, a constant tiring rhinitis, and although i haven't been diagnosed, lots of different people say i might have anxiety issues. When i became 14 my health started getting worse, allergy attacks, and breathing issues. This became the only reason why my parents had to start talking again. Idk if i have mentioned before but they hate each other to death. 

Now i'm almost 18, and the legal age in my country is 18, so my parents won't have any legal ties between each other anymore, but because of my health issues they still have to remain in contact, but they've indirectly decided to do this through me. So now, i'm kind of the middle man, every piece of hate and every drama between them goes through me. 

So what's this post about? i'd be nice to have opinnions about what should i do? In a position where i'm always sick and have to stand with parents that each time they see me, have to say bad stuff about the other to me.

They're not bad parents (although my relationship with my mother hasn't always been good, it has been a bit tense until almost a year ago) at all, but this thing between them two has been going for years, i've always been in the middle of it and i'm tired of it.
<bot>: Not so great in health. Parents hate each other. I'm the middle man and have to stand them having to share their hate with or through me.
