Structure and Cosmetics

I had so much fun in New York.
I was so happy, that it made me realize how miserable I've been.

I feel guilty thinking that this was the best birthday ever. Because how can it be, when my mom isn't here to hear all about it when I get home?

How can I just come back and be so sad after being so happy for 4 days? Maybe it was being able to be constantly distracted by someone and keeping busy...

I don't like being a miser.
