Do you have time to go for a walk for about 30 to 45 minutes, 3x a week? Voluntary exercise can help with the effects of depression and it will help with blood circulation and that can help with libido. Walking can tend to be good for processing stuff that is on your mind. Of course, when you are depressed, the last thing you will probably want to do is move. At all. So I understand that getting in the habit may not be easy.
