Well, it's over. It cost more but I brought in one of those services that come to the house. The vet looked her over and agreed she had many health issues. One being the seizures and said that indicated a strong possibility of a brain tumor. She had jaundice (the whites of her eyes were yellow) which indicated liver issues, a heart murmur, and the vomiting and weight loss made her believe she may have had cancer. She felt I was doing the right thing. I just didn't know "doing the right thing" could make you feel so awful.
My friends did call to check on me, and offer support. Both have called me family, and brother. Nice to have as there is so little of my family left. My friend Bill took me down to Village Inn as I hadn't eaten all day.
In any case, she can be with Mom now....
Thank you all for your kind words and support this past year, and if I don't get back here before then, Happy New Year!
