Birds, not butterflies

One second i was fine
another and the world was mine,
one more for the unspoken words,
here come the nervous birds.

There alot of moments in my life these days, where one second i feel completely fine, happy, good.
Then someone will say something, guess something, or i will freak out about something, stress about something,
and the next second i feel like i want to throw up, or laugh out my guts (Not is a good way).
Like Nervous birds are flying around my stomach, no not butterflies, because butterflies in your stomach, what a stupid idea. :P

I think it is just the stress of life and grade 12.
