Don't you ever hurt yourself. You need think about your future, with your own live, family and society. Try to think that you are very precious than another. You can do better in anything than another. First, love your Creator second love your parent and third love yourself. Dont fill your heart with useless people.
Don't trust people easily. You know your friend when you have a hard time. That's why the word friends are very underestimately. Please be careful of the bad friends.
Built your own confident level, so when people trying to change you style, it never happened
