Threatening my health for weight loss?

Just last week I was ready to buy and try the Laxatives as a way to lose weight. It kind of worried me because I was willing to deal with all of the bad things that come along with it. Im a 20 year old male and people always claim that I look great, but I dont see it that way. I eat right and exercise and yet I still dont look like the guys in the gym. Every time I see them at the gym I get angry and go run or workout for long periods of time so I can feel better about myself. Then my friend got angry with me and told me that I needed help. Is this motivation or do I have a problem?
