Unfortunately, I don't really have any solid advice to give you. I'm quite sorry. But I did want to say that I couldn't help but laugh a little when I read this part "Then I started to walk forward, and I tripped. I fell over, and I kept falling over. I couldn't walk straight without falling." For whatever reason it struck me as rather funny and gave me a good chuckle. So thank you it's great to start the morning off with a laugh, even a small one.

This might sound crazy, but if it happens again maybe try placing your hands in front of your eyes, imagining you'll be somewhere else, and then when you take them off the scene will have changed. I've never tried this, so I have no idea if it would be of help or if it would be the opposite.

Good luck!
