Oh, Twice. I am so sorry for your loss of sweet Abby. It is a loss that we all feel, although not anything near what I know you are feeling right now. When Aubrey passed away in May, it helped me to know that she was at the bridge (oh boy did I cry myself to death when I read Bill at Rainbow Bridge). It also helped knowing she was no longer in any pain or discomfort. She was no longer struggling to eat or get through a day normally. Just know that you did everything you could for sweet Abby and you gave her the life others couldn't through your hard work, strength, and most of all, love. She's just waiting on you at the bridge now. She's playing with Aubrey, Maggie, Gunny, and all our bully babies that have passed. She's strong! She's full of life! She's being the healthy dog with no worries we all wish she could have been.
I know it's hard to breathe, hard to think of her, hard to think of anything but her right now. I still think about Aubrey every day. I still cry over her loss. So far I can't really say that it hurts less over time... you just learn to bear it. You have a ton of friends here though and we will all be here for you.
