I hate to say it, but I think what she is saying can be possible. I am depressed myself, and have had people say I won't let myself be happy. At first it made me really upset, but the more I thought of it, the more I realized that it was possible that subconsciously at least I was holding onto the sadness because it was familiar, or I thought it was justified. Or that if I let it go, I was agreeing that the negative things that happened were good and acceptable. I don't know.
