why do people say they want to help you but do the opposite?

I am severely depressed. Like not in a way that isnt visible but like super fucking visible. Dont wash my hair, brush my teeth, stopped doing makeup like i look exactly how i feel. The only reason for it is having to go to school and having to work. I did not choose to be born. In my 18 years of living I was never passionate about anything, dont want a husband or kids or anything like literally just want to exist. I love being a homebody. I love laying in bed. I absolutely love every bit of it. I told that to my parents, my psychiatrist and school. But they are forcing me to finish high school but i just wanna be home like what the fuck i dont need to be hospitalised there is nothing fucking wrong with me I never fit in with people and have panick attacks whenever i try to act like they want me to. Not even years of therapy would change my mind because I know who I am and what I want. I will be happy to lay in bed and do basic house work for my parents when they work and thats it.

None of them want me dead but when i tell them the only thing that can make me stop being $u1c1d4L and at peace is to stay at home, cook for them and do house work they dont let me and its driving me insane i cannot stop crying and having anxiety and each day I'm just trying to survive like I am normal I just dont like interaction I am a human being and why do the force me to do something if it doesnt make ME happy. Like if my child wanted to end it and that was the only thing thst could keep them alive i would let them. I would do anything to keep them with me.
