Any ways to take my mind off the fact my daughter's in the NICU and make the months go by faster?

She's more than likely going to be there until June. I'm going back to school in May until she comes home and I'm on maternity leave for 6 weeks and the time is going so slow, it's killing me. If you were in that position in the past, how did you deal with the time before your preemie came home?
