Hello MooseMoose: (When I was a teenager... many decades ago now... we used to say, of something we liked or appreciated, that it was "cooler than a moose!")

I recall that, in your introductory post, you mentioned you're a teenager. But you didn't say how old you are specifically. It makes a difference if you're 14 or 15, for example, versus 18 or 19.
I think you're spot-on when you write that you can't change your parents... or replace them.

As a result, at least from my perspective, the only real answer here is to get out on your own... as soon as it is reasonably, & safely, possible to do so.
Others may differ.

But my personal opinion is you don't owe your parents anything. And you don't have to feel badly if you despise what they did to you. You're young & you still have the vast majority of your life ahead of you. Your "job", so to speak, is to live your own life & be as happy as possible. The bad part about carrying around a load of guilt regarding how you feel about how your parents treated you is that this kind of guilt & regret can be corrosive & can lead to depression, anxiety & unrelenting sadness as the years go by. You don't need that. And you don't deserve it either.
You've already learned that no one is going to help you with this. You've tried. So I think all you can do is strive to accept that your parents are who they are. But you are your own person & you can chart a different course. Start planning for it now.
