Are you close to anyone that has depression?

My husband is generally a happy, sweet guy, but he suffers from depression and is taking medication for it. The medicine doesn't always seem to help. He sees a counselor once or twice a month. Sometimes I just feel so alone and I don't know how to help him. His sex drive is low and it makes me feel unwanted, and I get overwhelmed because I'm the main "bread winner" and I feel like I do most of the daily chores. We don't have kids yet, but are talking about trying to conceive this year. I worry that it will be harder for us when we do have kids.
