Heading Toward the Rainbow Bridge - My Sweet Georgy Cat

I just got back from the vet. I'm so sad that I feel sick.
Actually I feel kinda numb and sad at this point because I had a panic attack while I was crying and felt like I couldn't breathe so I took a Xanax.

It's time for my Georgy cat to move on.
He's been with me for over 18 years.
But now he is suffering.
I was so young when I got him ... he's been with me my whole adult life.
He's had to deal with moving about 15 times during that time.
He's been with me during so many hard times. Cuddling with him has helped me so much over the years.
He used to be the happiest cat ... always overweight no matter how many diets I tried ... but always joyful and playful.
These last 5 years have been a slow and steady deterioration of his health.
He was 24 pounds...now he is 8 pounds.
He is now blind and mostly deaf.
He is showing signs of neurological issues.
He has a hard time walking and falls quite often.
He is no longer happy Georgy.
I feel that he is suffering, but as any pet owner knows, we have no way of truly knowing ... and this is the hardest part.
He still purrs when I pet him. He still wants to eat.
But the rest of the day he just cries... he can't get around, and when he does he falls.
The doc thinks the neurological issues are causing confusion so he is disoriented as well as blind.
He had a fever so the doc gave him an antibiotic and an anti-inflammatory for the pain.
This can help him not suffer as much during his last week.
I'm so sad and I have no idea how I'm going to take him next week to say goodbye.

I've had so many phones over the years. I don't really understand why the pics didn't move to each new phone, but I'm sad that I can't access all the cute photos I had of Georgy. These are the only pics I can find right now.
