Oh hon, noone is going to bash you! That was a very tough decision that you had to make. You said it right here
"Theres been something wrong with her since I've gotten her, I knew deep down inside there was". I've seen you type that you knew something was wrong several times. That's your Mommy instinct, and you have to listen to that. You did the right thing. Now Stormy no longer has to suffer. Big hugs to you and your daughter.
RIP Stormy
