I have NOONE who can check on him during the day

I hate that!! I thought and thought about that last night and this morning but everyone i know works full time days too and they all work too far away to be able to make it to my house on a lunch break or something!
I am leaving work at 3 to take him to the vet. But that is still 2.5hours away. I left him at 730am and I just feel for some reason that 730am - 330pm is too long to have left him alone today, yet I had no choice!
He was drinking water when I left this morning so I PRAY that hes ok. UUUgggghhh it really does break my heart!
