You are exhausted. You need rest and time to process all that has occured.
Quality of life is a huge consideration for many of us. It was my ONLY consideration when it came to my Buddy. I was determined that he would not suffer. Although I knew that releasing him would devastate me and break my heart, my decision had to be what was best for him.
Only you can determine what is reasonable/fair when it comes to Lena's care and how much she's able to handle. For now, I'm glad that she's home and you're able to spend some precious time together.
Hugs,
Kathy
