Climbing back up the slippery slope

My name's Chelsea. I'm only 18 but I'll be 19 in less than a month. I've always been overweight but honestly, I was content with myself for quite a good while. I carry most of my weight in my hips, butt and thighs, and people were always surprised to hear what I actually weigh due to how I carry it. I noticed that steadily, I'd gain about 5 pounds each year in high school. Still, I was fairly content. Until now. I am in my second year in community college and am weighing in at about 176. The number does not bother me, as numbers have never bothered me before. The problem is I no longer feel comfortable in my clothes... I spend a good amount of time putting on and throwing off shirts every morning because I can now see the weight I've put on. I have started wearing baggy T-shirts on a daily basis. I can see that my face is rounder. I know that I have already slipped on the slippery slope, and I am afraid of falling any farther... Before it was a "I'm happy mainting this weight". Now it's a "I need to get back to where I was before".

This ended up being longer than I intended
