I remember when I put my cat to sleep (10 years ago) and I wailed and sobbed so loudly people in the waiting room could hear me.
I think you were incredibly brave for facing that by yourself.
As for the sexual attraction. I agree with Rayanne...it'll come...give it time.
And right before my husband moved back home, I was terrified too...but I can tell you 3 months later...we are moving forward and I'm sooo glad I faced that fear!
