Hi GGB,
I just got back from spring break - sorry it took so long for me to respond! Since both you and Mrs. GGB seem to be dealing with depression, finding light-hearted moments within yourselves might be difficult. I would therefore reiterate my suggestion to find laughter from an external source. When you weren't feeling depressed, what made you laugh? Was there a genre of movies or books or comedians? There must have been something that you loved to laugh at. Spend some time remembering what those things used to be, and then make it a goal to do one a week (to get started) and see how you respond now. Laughter not only bring levity to your relationship with Mrs. GGB but it will make you feel better too!

As for your depression in how it relates to your flying, why don't you go to a doctor and talk about your concerns with him/her? There might be some steps you can take (without prescriptions) which will not cause you to be grounded. Getting the information is always the best course of action because it gives you options.
