I'm seriously starting to doubt my sanity

I knew I was gonna take the 11.15-bus and meet my cousin about 12 o'clock. Still, somewhere along the way I convinced myself I was gonna take the 12.15-bus. Which doesn't go on Saturdays!!

3rd big mistake in 24 hours... (the two other two being not talking to that guy and trying to publish the mega-post without being connected to the net.)

Okay, maybe not that big, bit it's annoying me.
