Am I supposed to be so jittery just barely a week into engagement?

2 consecutive nights, I woke up in the middle of the night.
And no, it is not I-need-to-pee-no-choice-but-to-get-up kind of waking up...
It's the bolt-upright-for-no-reason-whatsoever kind of waking up...
followed by toss-and-turn-and flip-and-flop kind of insomnia...

So although I tuck myself into bed at midnight, I find myself sitting up and wide awake at like 4am
And my brain + body refused to go back to proper sleep after that...
which explains why I am blogging at 741am on a Saturday!

Thoughts are zooming around so fast in my head, I can't remember what I am thinking about...
And then suddenly, I'll break into cold sweat...have palpitations and it'll take alot of concentration to get myself back into semi-conscious state
The thoughts will then come zooming back and the cycle repeats..

The last time I am this nervous, I was losing sleep over my final clinical exam in Melbourne...

So...is this like a final clinical exam for my singlehood...hence I am such a nervous wreck?
