I went through severe depression too back a few years ago. I've worked hard to get healthy and strong. I started doing it to try to save my M, but eventually at some point just started focusing on me and the kids. I think you need to not even think about your H at this point, but yourself, getting yourself strong and healthy. If you are still depressed after a month or 2 on an AD, I would try to switch to another.
Also, if you don't have your DR anymore, then go to your local library and check it out or any of her other books I would recommend (except for the Sex-Starved one which I haven't read, I think all her books are good). If they don't have it, then you can also Interlibrary Loan request for it, and that might take a week or 2 but well worth it.
Keep posting here. Are you continuing to get IC each week b/c that's important? I still see my C, but not as much anymore, but it was crucial at one point. Do you exercise at all? Anything is good and will help, walking, biking, whatever. Karen
