I'm new

I'm new and am not quite sure what I'm supposed to do here yet but I need a place to put my thoughts and get things off of my chest that I am dealing with. I am severely chronically ill, I have been since a child. I am totally dependent on my parents and cant get away from them, although I desperatly need to. They are very controlling and it makes dealing with my illness and them incredibly difficult and I just dont know what to do.

My health condition is very bad, although I've spent all my life trying to find treatment and a clearer diagnosis things have got progressively worse. I have missed out on school, college, work, life in general. I dont have any sense of normalacy. I am unable to care for myself and depend on my parents to care for me, so it's incredibly hard to stand up to them, defend myself or argue as, well they control my life basically.

I dont know if I am doing this right, but I am using this space to vent. Although for a lot of the time, just typing and putting these thoughts together are very draining to do. My mental health gets pushed aside since my physical health is so dire but I am in a bad place. Im the type of person to always look at solutions and a way to work on fixing things. But I can't see a way out of this.

My parents dont abuse me and i feel like i am going mad a lot of the time with them. Like if I say any of this stuff no one will believe me and tell me I am being selfish and wrong. But its very much about mind games and control. Small things like, me not being allowed to organise how my own room/possession are. Or things like shaking the car keys infront of my face and telling me, if I want to drive my ill pet to the vet myself then go ahead and do it. (I can barely walk let alone drive and can only get about outside via wheelchair).
My mum is telling me she's a slave, because of me, all of the time, because she is my carer. If I dare disobey or question something she does, she tells me I treat her like a slave.

I truely never want to rely on anyone or ask anyone to do anything for me ever again in my life.
