Missing him...

What do you ladies do to keep yourself occupied when you miss your husband/SO? I work part time and go to night school full time, but I still find myself with several hours in the day that I am alone and I miss him greatly. He works damn near 24/7. I study, clean house, watch tv, talk to friends...but sometimes I just find myself being overwhelmed by how much I miss him, and it hurts. I dont have enough money to be driving around town and shopping or exploring, let alone enough gas to go visit a friend or go to yoga class like I want to. So, I'm typically stuck at home and I get lonely and depressed. Are any of you in the same boat or have been before? What kept you occupied and feeling productive? I try to be productive but I find that my missing him gets in the way...
