Girl: Why are you wearing sweatshirts in hot weather again?

Me: (I don't want to show you anything) I'm okay.

Girl: You look tired, are you sure your okay?

Me: (I've always been tired and you now just realized?) I'm fine.

Girl: Do you want to go to the beach and wear swimsuits?

Me: (No because I hate my body) No thanks.

All these question I get asked and I still can't tell the truth. Why?
