You and I have talked before, but I’m going to go through your post point by point.
1. Anyone who repeats a year due to grades can’t fail anymore classes. You're not the first, you won’t be the last. I know repeating students who came back and did so well they were asked to be tutors.
2. Presumably you have a bachelor’s degree, correct? So if medicine doesn’t work out for you, you still have a degree, just not a medical degree. No more catastrophizing about that please.
3. PA is not a backup plan for MD/DO. It would probably take you at least 2 years to get into a PA program because of the extensive clinical hours requirement, and as many have said, they don’t like to be used as backup. Med school is Mexico is not a backup plan...step back and think what you would tell a friend if they asked you for advice about that. If you need a real backup plan to hold on to, consider epidemiology (MPH), perfusion, or NP. All these take time and more school/$$. Your best bet is to stay put and systematically work through your difficulties in med school, until you’re either successful or
4. You’ve probably been given more advice on this forum than most, but I’m starting to see a pattern that has me a little worried about you...you’re panicking, and grasping at whatever you think will save you. I understand! It’s so hard not to run around trying everything when you feel like nothing is working, but you’re changing too much too fast. You’ve been given great advice on what to cover coming back, and not going into medical school blind is a gift and an opportunity.
I second the recommendation of a learning specialist and possibly a therapist or someone who can talk you down when you start the crazy cycle again. I think some professional advice and accountability would help you focus on one thing at a time until you’ve addressed your problem areas. Until you do this you’ll have trouble no matter what program you end up in.
Dhooy, we all care enough about you and your future to come here and write out lengthy advice. Your mom cares about you and your future too. Whether she’s trying to protect you in a way that’s detrimental is for you to decide. Personally, I would take all this advice, go see those learning and psych professionals, and then go spend some time ALONE, thinking through my options, and making the decision that’s best for me.
