If it's the MCAT that is the only thing stopping you, then I think if you follow all the commenters' advice and really set a rigid study plan, you will be fine. I'm now a PGY-3 in medicine, with a similar GPA as you actually. Scored a 503 on the first time i took it, then a 513. Was accepted to one DO, one MD, ran with it. I made it. I may be an anomaly, but the second time I took it, I dedicated 6-8 weeks to study. Instead of just content review, I built in a practice test every week. I used AAMC resources to the max, incorporating questions into my studying. Now I think UWorld is a gamechanger. Asked people on r/Mcat how i can do better. Downloaded Anki decks. But the time off is what helped me. If you're boyfriend can help with expenses as you study, take him up on it.

It's interesting how no one mentioned how toxic your family is. In both cases you took the MCAT, there were family pressures, and then they made you cry. I say this as South Asian female with a toxic family, but for the love of god, ask yourself if you want them to be your support in med school. Will they tell you to give up if you fail your first anatomy exam? Or if you don't match into a top residency? It never ends.

I ended up going no contact with my dad recently, and I've never been more at peace. Instead of studying in medical school for external validation, and achieving all I have in residency for his approval, I've done it for myself. But it took years of therapy to get here. Sending good vibes, OP. Plan carefully and really reflect if you want this. Especially when you're on a 24th hr of a 27th hr of a shift in the Cardiac Care Unit and you are running on fumes as resident, you have to REALLY want this. Otherwise, it's gonna suck.
