Maybe you could get into a routine of a good, long walk when you get home. That will give you some "together" time, and give him some much-needed exercise. It will be good for both of you!
I was also thinking of family or friends who live nearby...especially if you know someone who doesn't work, or who may be a little older, retired, or on their own. They might enjoy having that time for a special visit.
My last thought was...I know that money is tight, but if you have a pre-teen or teen who lives nearby who is responsible, maybe you could pay him/her a small amount to come and walk Wookie, and play with him for a little while. Kind of like a "mother's helper".
Good luck! I'm sorry you're going through a tough time, but I am sure everything will work out. Our dogs love us no matter what!
