<human>: 26 y/o female, sw 150lbs, goal weight, 130 lbs

First off, I'm brand new to this sub, so I hope I'm doing this right...
I've been struggling with myself for quite some time, searching for the motivation and the courage to do this and to better myself. I finally signed up for a spin class and was very excited to get on the road to becoming the person I've always wanted to be. I live in NYC and had called a cab to take me to my first class, which is starting right now. Cab got stuck in traffic, and I missed the class. I was so nervous to begin with, and I can't help but feel defeated that I can't even get to the freaking class. I feel silly being so upset about this, but I really just feel like I've failed before I've even begun.
