Everyone excludes me?

you have to be confidence,and be happy,love yourself,dont say that your a freak or something like that,you gonna get your selfsteam more low,dont cut yourself is not worth it,try talking to people a lot you gonna think at first that is awkward but actually there is gonna be somebody that want to be your friend and gonna like you for who you are; look in the mirror everyday think things like your pretty,your good enough you can do anything and you will get better.
