To me being sad is like smoke that settles around you. Its wispy and sneaky and can get into the crevices of your heart and mind and its so incredibly HEAVY. The good thing about it is ~ its smoke and it will dissipate and go away. When I get sad for no reason I go outside and spend some time in the sun and the air. I try to get up a little earlier before it gets too hot and just enjoy the silence of outside. I wish you well my friend...its hard sometimes because you can't really explain why the sad is there...A few times even loosing myself in a quilting project is all I need to zap it away...other times that doesn't work. A good long hard cry sometimes will help.... =)
