My ex wife had major depression. I have BP. We did not really do a very good job of caring for each other; my depression got real bad, and she pretty much left me as a result. I would offer that if you have someone who loves you, hold on to that love. It is strong, and will be like an anchor for you in dealing with depression. It used to be that way for me... I had someone who used to understand what it felt like to be depressed. She could help me out of the darkest places, with her slightest touch. If you have someone who you trust, trust them not to leave you in your time of greatest need, and try to connect with each other as much as you can. Tell them that you're suffering too... listen, and be listened to. This is what my ex and I could not do, even though I knew I needed to do it...

I hope that helps.
