18 Year Old With 75lbs

Hi there everyone! My name is Erika, but I go by Finn, and I'm looking for some guidance on this life style change. I haven't always been the bigger girl. When I was much younger, I ate whole pizzas, and played video games, trying to fit in with the guys and do as they do. But when I hit sixteen, I developed serious depression and anxiety, and was put on pill after pill. I ate, and ate, and ate, bringing food into my bed and eating at night, and never once stepping foot on a gym. From 125lbs, I became 210lbs, getting out of breath when I go up a few flights of stairs.

For the longest time, I've had the spark to do something, to change, but the spark was only a spark, and I always slipped back into the same routine. Now, the spark is a full blown fire. I've been starting to run, and counting calories, and tracking everything and anything that enters my mouth. I don't eat anything after dinner, and I'm trying so hard to lose it.

I know it's a change in lifestyle, and I want to, more than anything in the world, become healthier, and to one day run a whole 5k. You can laugh, people run 5ks easily, but for me, it's a challenge. Is anyone willing to be my fitness buddy, or just give me any advice they learned the hard way, or even motivation?

Thanks guys, you all inspire me to be better and work harder.

Love,
Finn
