Cramp entry - 15 lines

Today at work, at my wit's last end, I found a glitch in my memory
My computer betrayed and mocked as my password escaped me.

To ward off the negative mood and get some endorphins flowing
I headed to the gym, but my frustration really started growing.

My locker combination had fled too. Why, oh, why?
At this point in the day, I just wanted to cry.

I pulled myself together, got a grip, got a hold,
And said to myself, "You're not crazy and you are not old!"

Then tonight convinced it all been a hoax,
A question stopped me quick from the one I love most.

Where was the answer that should have been in my brain?
I could only conclude, nope, I must be insane.
Surely tomorrow would be better I told myself in vain.

Yes, tomorrow I would remember - tomorrow, you'll see.
I'm not getting older or crazy. Yes, tomorrow holds my memory!
