I need motivation

I've found out that my high school reunion is in July. I really want to be at my goal weight by then. I'm at my high school weight now. I've been working really hard since January and have already lost 13 lbs. I have finally reached my goal of 50 lbs. Now for my next 25. I'm going to keep track and do weekly updates. I figure if I have to account for my weight maybe I'll do it. I put an app on my phone that helps me track my calories and exercise.
