22 y/o, 5"5 and looking to lose around 20 lbs!

I'm so excited to finally buckle down and nip the weight gain in the bud. I was 120lb in high school and now after graduating college I'm an unhealthy 142. About 9 months ago I was two weeks short of finishing insanity and I injured my knee, I was 130 lbs and completely stopped working out and surprise surprise gained 10 lbs. I'm starting this journey once more, no quitting! I'm currently doing Turbo Fire and am looking for some support. I'd love to have a few friends with similar goals!
