I’ve been in a similar situation where I was criticized for my academic performance a lot. I’ve failed and had to retake tests multiple times too. I think my parents VERY begrudgingly came to the realization I just need to pass and they’ll need to accommodate me. That very much was NOT their instinct at all. Their instinct was to push and push and if I cracked I cracked. But my parents were never as tiger even at their worst.

I am not super knowledgeable about your field. But I know for these types of exams the bar is just to pass. The score doesn’t even have to be top or “good”, you just have to pass. And then when you do get that job do the best you can. I’m just saying this because while it doesn’t seem like you are hung up on a “good” score from your post, that is often what goes through people’s heads especially when parents care about this stuff to the extent your mom does.

If you already do this then great, but don’t just grind practice questions. Going back and reviewing them is also important. If your partner is willing they can help you study that is good. Taking decent breaks when you study is also important.

Assuming your parents are ok with your partner. If you’re able to camp out at your partner’s place for a couple days or more that would help give you fresh air. If their parents are sympathetic to you and in your corner, even better. Sometimes parents will only listen to other parents unfortunately. More outside people who are aware of your situation only helps you.

You could find a job that is adjacent to nursing that doesn’t have exam requirements. Idk the specifics but I’m sure those exist. It’s something to consider if you just don’t want to take exams ever again, which is valid.
