HT,

I think you should stop talking about sex altogether, and instead have her focus on using physiological means to get out of her depression or whatever you call the state she is in. Then if she improves her physiological response, you can perhaps hope that she can get some drive back.

So: she will need a regular sleep schedule, with Melatonin at night and going outside in a sleeveless top and shorts, wearing a hat and sunglasses, each morning to be in the sun for 20-30 minutes, moderate coffee consumption before 3PM, no sitting in front of the computer (she should be on her tummy on the floor or couch), limit the total hours in front of the screen, in bed by midnight at the latest, getting up same time each day, preferably on her own without an alarm clock. Sounds draconian, but she has basically self-imprisoned, so she needs to get herself out of her current state.

And if she gets better, then maybe resume your conversations about sex, since, right now, she is, basically, half-dead, and you cannot expect much passion from a person who is half-dead - you might as well try getting blood out of a stone.
