when someone is told something good about them self it boosts there self esteem, when someone is rude or ungrateful towards someone it lowers there self esteem. the time I was told I look good with short hair and to not care what people think and that I'm pretty and awesome without long hair made my self esteem go up!! but when girls choose to not be my friend because I shaved my head it lowered my self esteem pretty bad where I was at my breaking point...
