Hi Brittany, and
"Determination" is the very quality you need so glad you have it!! You CAN do this!!
I could not help but notice that we are close to the same height and I started out just a bit below where you are, at 306. And I am a lot older so that makes it harder. So you see it CAN be done!!
It is soooooooooooooooooooooooo worth it!! Hope you decide to stick around and work out an eating and exercise plan, etc.
