Not everyone is going to like you. In fact, there will be a lot of people in your life that can't stand you. Their not liking you has much more to do with the issues of the other person instead of you. People will treat you poorly and discriminate against you but it is your attitude that will get you through.
Remember that you are a person of value and worth! You have to be your own best friend and cheerleader. When others are treating you in a negative way than change the narrative. This is your life so you are the narrator. Stop letting other people be the narrators of your life!
Here's a picture quote you should put in a place where you can find it easily when you are feeling excluded by others. When feeling negative read this quote & remember that you are AMAZING!
BTW if you don't know who Zora Neale Hurston is than you should really learn about this wonderful woman!
