What are good pick me up activities to do while pregnant?

I am 28 weeks pregnant and unfortunately the company I work for keeps cutting my hours the more pregnant I get... I think I am down to 13 hours this week. Since I am at home most of the time while my fiance is working, what are free pick me up activities I can do for myself. I am starting to get depressed b/c no one wants to hire a pregnant woman, and I cant seem to get any hours. So I dont have money to spend on these activities. So far I have thought of: reading a book outside (to get some color to feel better about myself and keep my mind busy) but thats really about as creative as I can get. Oh and taking walks.
