I'm sorry for the trouble you've been going thru but am very glad you didn't drink over it.
Life has its ups and downs and it's hard to deal with it sometimes but drinking will only make things worse.
I hope you have a good vet for your dog. My one dog went (nearly) blind over two years ago but still has a good life as I guide his steps and make sure there's nothing dangerous he could get into. And being a dog, he doesn't feel sorry for himself, just enjoys his life - which is the life of a king.
Take good care of her and stay sober. I hope things get better for you.
