Could the depression be from 2 things that are now gone? Not saying you miss them, but they put out more than just testosterone. A few days after mine were gone, I didn't miss them, but something didn't feel exactly right in the world either..
Btw, you are off the estradiol for a while? Did you have a withdrawal from that too? Now that it's my dominant hormone, the world is soo sad without it.. I know it affects us differently. As long as you know your feelings, maybe you can reason through them until you get back to your routine..
Call hubby when sad, maybe that will help;) just remember that deep sadness can also have anger. Things that used to be petty to you could be an earth scorcher.. hopefully this will not happen to you;)
Sweet dreams, and glad to see you out and about!
