Advice regarding foreclosure/spouse debt

My husband owns a condo and is upside down on the mortgage. There is no way to sell it. We are not late on the payment yet. I am in grad school full-time. We have a daughter who is almost 2. Since her birth, I worked part-time and we were managing paying our bills. But I CANNOT work since my school program is super full-time. I have a lot of credit card debt, but have never been late. My debt is in my name. My husband does not have credit card debt, but has the condo in his name. We cannot afford to live here anymore and do not want to live here anymore. Since I'm no longer working, his income is barely enough to cover all my credit card bills, the car payments, insurance, groceries, daughter's childcare, etc. We were thinking to continue paying my bills so that when I graduate and get a good job (pretty much guaranteed as a Physician Assistant), I'll be able to buy a house in my name since my credit won't be affected by a foreclosure. If we pay the house, we do not have money to pay my bills and my credit will be wrecked. Then we'll still be under this condo that is never going to recover its initial value.

What is the best way to walk away from this condo? Morally, I hate to do this, but I don't feel we have another choice. Thanks in advance. We're in Michigan, btw.
