If you think that Law school is a serious possibility, which one of these three sets you up the best financially? If you choose W&M or W&L, would your parents put the money that they would spend to send you to WUSTL aside for law school? If the money for WUSTL would require debt, I would drop it from consideration: you have 2 top schools who will give you a debt-free education. Your future self will be more grateful than you can begin to imagine!
IMO, aside from the financial angle, this is a wonderful opportunity for you to practice listening to yourself: there is no ‘wrong’ choice here. Assuming no debt, there isn’t an objectively ‘better’ choice- it’s about which is better for you. This is a moment for you to stop asking other people, and ask yourself: ‘where am I most likely to shine?’ and ‘where do I want to live for the next 4 years of my life?’.
Learning to trust yourself is a big part of moving into adult life- you can gather info and opinions endlessly, but at some point you have make a decision, and trust yourself that you have 1) done your best to figure out the best (or more often in life, the least-bad!) option and 2) you can handle fixing it if it doesn’t go to plan (b/c sometimes it won’t).
tl;dr: I think you already know what you want to do. Trust yourself, take a deep breath & jump: you’ve got this!
