You are not a failure. For one thing, you are fighting BP and are still here, and that has to count for something.

I often feel like a failure. No job, no job history even, a bad wife & mother. I'm horrible at housekeeping, hate cooking and daily chores. I can't get involved in my daughter's playing, and now she is into computer games and even computer coding that my husband introduced to her and I understand zilch. So I relate to her less. And there are days when I can't get out of bed or overexercise, what kind of body image does that setup for a pre-teen young girl?

You are hanging in there. I personally think mental illness is one of the hardest battles in life to fight, especially things like BP, when you know the odds are that you will be battling this disease for the rest of your life.
