First order of business is to talk to your doctor. Medications often impact libido. If your loss of sexual desire preceded the meds but came after the depression then that's another thing to discuss with doc.

I've posted advice on this topic elsewhere and the theme is generally the same. Sex is rarely the problem. It's usually a symptom of the problem. With animosity or resentment comes a lack of desire to be intimate with someone. Fix the problem and the symptoms will go away.

Complete surrender should not just come at moments in which one faces overwhelming odds, but in the calm when it seems one is personally in complete control of one's life.
