SG, what helped me was when I started reading. I started with children's/fantasy novels as they addressed my issues best but it was interesting to see how one of my symptoms got "less" as the reading got more and then, over about 10 years, how the reading changed from fiction to non-fiction. I think the combination of therapy and "life" helped. But reading and journaling helped me find other interests over time. It was very hard for me too as I was use to my stepmother ruling my life and had spent that whole life in "resistance" to her so had trouble turning around and doing "my own" thing. I had to learn to "want" for myself instead of just "don't want" what she wanted for me :-)

You might try working with Julia Cameron's The Artist's Way http://www.theartistsway.com/ or other similar "workbook." That helped me the most to tease out my creative skill(s) (for me it was writing) and get the creative juices flowing so I could think more "broadly"?
