I'm sorry that your wife isn't able to understand more of what's going on with you... though glad that she cares enough to try. It can be tough, for anyone, to try to get your head around someone elses' experiences if it's not something you personally experience as well...

And, glad the concrete things are helping - I totally know what you mean. Sometimes when I'm in a weird mood or depressed, something very concrete helps me focus and get to a saner, more solid place.

And, yeah... it sounds like talking to your T about the feelings might be useful... good luck with it! I hope it goes well!
