I think for me, it is my kids. I have to be strong for them, they depend on me, and I need to help them through life. I can't just collapse and be totally depressed and non-functional. Even during my worst depression, I kept going for them.

I think also at heart, I am an optimist, although I hide it well. I always think the best of people (even when others tell me they don't deserve it) and I guess somewhere deep inside I feel I have the right to be happy.
