Insecurity or Egomania?

I have an artistic friend who is only happy when she's creating something, writing something, or thinking something profound. She writes poems, creates jewelry, would like to paint. She doesn't have much extra money lately and I've noticed she seems contemptuous of other artists lately. At the craft store, she says, "well anyone can do that. If you have money, you can make all kinds of stuff. I wonder how much soul people put in their work and how much of it is pretentious, just for show." I took her to a bead shop and she walked out sad and said, "I don't want to be around those people--they have no clue. Just a bunch of bored rich housewives killing time with another hobby." She has written beautiful poems that make you wonder, think, cry--it's sad to see her this young and jaded. How can I help her out of this state? Unless it's deep, she's not interested. I try to get her to laugh and she says "I could smile more if I knew everyone was smiling too." How do I get her to be light?
