Britney,
I have not been a glass is half full person in a long time. That is part of what I hope to attain from my journey. Not sure how far a transition it will take.
I too have a fairly supportive spouse. However, I am going very slowly and it gives one lots of time to go back and forth. I call it yo-yoing. Since admitting to myself and then coming out to my wife, I have done a lot of it. I have no solutions for anyone. However, I am becoming more positive in little ways.
I can only hope it is a short time you feel down. Maybe you can come up with some distractions for the next bout.
With warmth,
Joanna
