Dear wee Sally, I can relate. I work on the weekends now and it seems that I live to work but that's ok. When I don't work, I sit and rest in my desk chair most of the time.
Just try to figure that you put in your life's work and you have time to sit and rest and visit with your online friends.
Maybe join an online dating site to get some excitement in your life?

... Even if you don't actually date? Just a thought.
Or, call your contruction hunks to come over and do an estimate for some sort of work around the house.
Feel better soon little Sal.
