Dude. Do あなた mind if I call あなた Dude? あなた shouldn't ask または have people tell あなた how to change. Just be yourself.. あなた really shouldn't care what others think of you.. They only opinion that matters about yourself is your's. あなた shouldn't change just because someone tells あなた to.
We can't not help あなた nor suggest how to help あなた change, あなた must figure it out and do it on your own. But only do it if あなた really want to, it's best to be yourself no matter what, don't changes for others, if someone doesn't like あなた for who あなた are, then don't be フレンズ with them, that simple.
