I agree with you that Case Western is the sensible choice and you certainly won’t be sacrificing anything academically going there.
Once you commit to Case, feel free to absorb all the “ick” you can about Michigan, lol. For instance, my daughter there lives with three nursing students. They each have to have a car after sophomore year and they can be assigned to clinicals 45+ minutes away. That can be inconvenient and expensive, adding a big chunk to what would have been your already pricey bill. Also, even though you are in Cleveland and Ohio State is in Columbus, you will meet plenty of Ohioans who see Michigan as the enemy. Soak it in and believe what they say.
This may all sound silly, but there is no reason to look back once you commit. You can have a great experience at Case even if it is different than what you would have had at Michigan. Be open to the opportunities and don’t look back or compare.
