My bf is the same way when he drinks too much. I would say maybe you kind of let that night of drinking get in your head and its pysching you out now. Just relax, I'm sure its nothing medical other than stress/nervousness.
So, so you think you can tell Heaven from Hell,
blue skies from pain.
Can you tell a green field from a cold steel rail?
A smile from a veil?
Do you think you can tell?
And did they get you to trade your heroes for ghosts?
Hot ashes for trees?
Hot air for a cool breeze?
Cold comfort for change?
And did you exchange a walk on part in the war for a lead role in a cage?
