My sister is a recent cancer survivor

. However, lately she has become so depressed. She is really tired, which is understandable due to her anemia, but she is finding it very hard to function. The least little thing sends her into tears. She's very discouraged that she doesn't have enough energy to function. She has been on Paxil for about a month, but it doesn't seem to help. Are there support groups for those with her situation? Could a change in diet help?
