Venting I can’t do this anymore

[FrownyFace]

I don't know what to do anymore. Last March, I had appendicitis. My parents had just lost their health insurance, so I had to go in without it. Later I got a bill for 23k+. I have fought them for months and months and unfortunately, I don't qualify for assistance because I make too much and they won't negotiate. The stress is too much. I don't want to be sold to collections and I don't want to have my life ruined by them suing me. And I'm just being led in circles. I feel like the only way out of this is to end it. It's not the only thing fucked up in my life, but it's the most out of control and it's just like the final nail in the coffin.
I'm scared to leave my dog because my family doesn't respect anything I have, but I don't want to do this anymore. I just want to rest and not feel like my life is (ironically) over anymore. I'm sick of this fucking world.
