Tired and grumpy

Couldn't fall back to sleep last night after I got up at 1:30 for a cat related issue. I lied in bed for a bit, then got up and did yoga and meditation, read a bit and then watched some TV. I am fueled currently with my usual two double espressos but augmented it with two cups of tea. I am tired right now and I am trying to keep my distance from folks because when I am tired, I am grumpy. Work is also getting on my nerves, and that was yesterday when I wasn't tired.
