Oh God.....hun, there just AREN'T any words...
I am SO SO incredibly sorry that you lost your sweet baby. Oh my gosh, I can just feel your pain and heartache in your post

My heart is literally hurting for you sweetie

I am honestly crying over this because I am trying to put myself in your shoes - and the pain is unbearable

Can I just say to you though? PLEASE don't beat yourself up over this. You took her to have something done that was going to HELP HER....she was going to benefit from the cleaning....you had NO idea that this was going to happen....
IT IS NOT YOUR FAULT. Please keep telling yourself that over and over again, "It is NOT my fault".
I am sending many many thoughts and prayers your way sweetie. I am honest to God SO SORRY that this happened to your sweet baby and please know that we are ALL here for you to offer support

If you need to vent and let out your anger and frustration - let us have it. That is what we're here for.
R.I.P. To your darling little angel
