Can't sleep

I really miss my Maddie...I've been crying all day and night. I can't sleep, I was so used to her warm body in-between the covers and her curled up behind my knees. This is worse than a dog dying...because its hard knowing she's still out there, without me, me without her. Chris keeps assuring me it was the right decision, but I don't know if I feel that way anymore. Guess it doesn't really matter how I feel though right? It's too late now.
