Weight loss

What are some things that motivated you guys to lose weight? I’m currently at my heaviest weight and was very skinny as a little girl. I’m very insecure and I just don’t feel comfortable anymore. My back aches and my clothes don’t fit properly. I also don’t know how to start living a healthy life. I am extremely lazy. I’m a full time student and a part time worker that lives at home w my family. We share one car so I’m the one driving everybody around every week day. I want to take some time to myself to focus on me!
