Would I lose weight if I exercised till I felt extremely exhausted every day?

Well if you are goung to push yourself that hard, you are more likely to give up because its a chore and a pain to do. No one should exhaust themselves to the point of fainting to work out to become `thin`. And what you said about looking like a `fat pig` is cruel. Not everyone is built the same and some people cant help it that they are as heavy as they are or have other problems that make them heavy. So, you shouldnt say things like that no matter if it was a joke or not. Youre already thin, and youre probably one of those girls that will always think they are `fat` even when they arent. So dont kill yourself working out. If you over do it, you could get really sick and potentially cause problems with your heart and or lungs. I honestly dont feel bad for you and i think you have some self esteem issues. So suck it up and love yourself for who you are. Dont try to impress others by the way you look. You may feel you need to be thinner to fel better but thats not the case with a lot of people.
