What is wrong with me?

I can't remember stuff anymore.

I'm deadly serious.

It's worrying me.

I was so looking forward to Tommy Baker's puppet show tomorrow.

Trouble is it was last feckin week.

I walked into the kitchen to boil the kettle. It never happened.

I was supposed to me a good friend for lunch. He went hungry.

Is it medication? Degeneration?

I really don't like this...
