I don't think I'm close enough to my T yet to feel that way, but I can relate to feeling "unreal" around people in general. It's hard when you have a lot of intense stuff going on, but you can't really share with people (it's not always appropriate, they may not be that supportive, they may not care, etc.). It makes me feel very unreal too... even just talking to people about what's going on, and not being comfortable telling them about therapy (since that's the biggest, most important thing going on for me right now!).

I wish I had an answer for you! I think your ideas (journaling, talking to your wife, playing with the dogs) are great... does your wife know about the stuff you revealed to T? Is she a good person to talk to about feeling "unreal"? I hope she can help you feel heard and solid and real.
