You have to feel pity for those people. What must it be like to live your life like that? I'm generally not a whiny person, but on my rare cranky days, I just shut up. My husband teases me about it. When I know I am totally irrational, I just don't speak. (I'm pretty sure it's hormonal)
My husband's ex-wife is a professional victim type. I keep hoping for her sake that she finds some joy in something. Anything! For me, it can be as easy as looking at some of the quilts folks make here, or a good cup of coffee in the morning and a kiss from a shy dog. I think the less than rosy times in my life have given me opportunities to find the blessings in the small sweet things in life.
