What am I? Unacceptable!?

I know what I'm suppose to do. I've done it! So when people are telling me this it just makes me made.

If it's me saying that I need to get in shape for my health or to loose weight that's one thing. That is me. but when others say it it just makes me feel like I'm unacceptable to them. Like there is something wrong with me. What? Am I not good enough for you? Are you not happy with me? Do I not fulfill you even though I'm fat?! What!!????

I have done it. I went from 198 to 148! I was almost my high school weight! I know how to do it. I know what to do to get there so leave me alone!!!!!
