Hoagie is getting worse

Hoagie gets weaker every day.  I feel him slowly pulling away from us.  He can barely get from one room to another without having to lie down.  It is breaking my heart and causing me high anxiety. But somehow he is still purring, still eating.  I don't think he'll be with us much longer and I wonder if I'll have to make that heartbreaking decision this week.  That or wake up to find him gone.  Both things fill me with dread.  I am now on Xanax to try to handle the anxiety and it works a little bit.  I'm having nightmares, though, and am not sleeping well.  Only keeping busy helps me deal with this.  I am still healing from my accident as well, which doesn't help matters much. I HATE DEATH!  I HATE LOSS!  I've had too much of it...I need a break!
