Butterflies, really?

Again. My stomach has something against me. What even causes butterflies? Let's wiki it.
...
Butterflies in the stomach is a medical condition characterized by the physical sensation of a "fluttery" feeling in the stomach. This sensation can be a physical sensation related to the body's fight or flight response or it can be an ineffable experience related to the psychology of true love or nervousness.
Some believe that this is caused by the release of epinephrine (adrenaline) when one is nervous, pulling blood away from the stomach and sending it to the muscles. This reduced blood flow, in turn, causes the stomach to temporarily shut down, and possibly the reason for reduced appetite during love sickness. ~Wikipedia
Well, that was informing. Is that the right word? Now I'm informed about butterflies... Whatever. So, either I'm lovesick or nervous. Or both. Or neither? But then why would I have butterflies? I'm just adrenaline-pumped? By laying in bed writing a blogpost? I don't think so.
I'm just anxious for Saturday. I don't know if it'll be good or if it'll stink. Also Sunday.

Oh! Good news! I got my license!! What!! Dunno when I'll be able to drive by myself, though.
I should go to sleep.

Okay, good night. I don't have much more to say. Except Saturday can't come quickly enough.

Love,
