Oh, Zorg. *hugs*
I lost someone I loved once. Though she didn't leave me, she was taken. I know what it is like to live with sadness everyday. Some days it gets worse. Some days it is only a dull ache. Then you see something and all the ache, all the hurt comes rushing back.
It hurts. It cuts you at your soul. But I would not trade all my long years of sorrow and sadness to replace those few years of utter happiness. I know the two stories of ours don't exactly parellel, but I have had to learn how to deal with sadness over the years. If you ever have a need, just let me know. From crying, to pining. From bliss to miss. I am always open to talk.
