Want to lose 30 pounds ( but need motivation)

I used to be big on weight lifting and eating right all the time. I used to take drugs for building my body and shakes. I spend hundreds of dollars. I was one of those crazy health nuts. Then I stopped because I had no reason to be like I was. I let's my self go for 5 years and look at my self and feel like a loser. I have low energy and my weight is hurting my legs and body. People at work call me fat *kitten* and lazy. I'm done and sick of it I was 200 pounds and 10 percent body fat know I'm 260 and my legs hurt and my body has little energy. Someone please help me!!!
