DC..I know the feeling of the stress that work puts on you. I did the same thing you have done, bring the work and stress home.
What I do now after a stressful day before I come home,(and if)before I have a beer,is to:
Stop at the front door. Take a deep breath..or two..sometimes three. Say a small prayer that its just work " I can handle it." Think positive thoughts or what positive thing I can say to the wife and/or kids. Remember to ask wife how her day was before any other questions or gripes. Put on a smile. Enter...
Just the smile and deep breaths alone can change my attitude quick. Once the positive vibe is shown off, W and kids are happy to see me. In turn they make me happy. Then work is all but a faded memory till the next day.
Find what does work, for me the above does.
As for being the home body, I too was the same. I still like to be home, but did find some things that the wife(and kids) and I enjoy together. Is there something at home y'all do together? I found that watching a show my wife enjoys and talking about it after wards makes great small talk. This worked extremely well we were seperated and started slow. Y'all could find some other hobby to enjoy together, even if it is something simple as a walk together.
