First off, I’m so sorry you had that much pressure put on you in school. Your father should have helped you and instead he needlessly made things harder. One thing you should keep in mind is a saying I see every now and again: “Comparison is the thief of joy”. You’re not your brothers or your sisters and that’s okay! You may have the same parents, but that doesn’t mean you have to be clones.

Distancing yourself from your abusive father was a good move and I applaud you for that! Parents who don’t accept their own children, especially including their quirks and flaws, don’t deserve them. It sounds like he wants you to be someone else, but tough shit: you’re not them, you’re you. And you have zero obligation to become this perfect person in your dad’s head.

And to answer your question: yes, there is hope. You got out of a bad situation and it sounds like you’re still recovering. For now, forget math, grades and employment and just focus on getting better. Good grades and a stable job don’t mean jack shit if you’re miserable anyway.
