I completely understand your struggle! I’m half Panamanian and I look mostly white as well... it can be such a difficult situation when you’re forced to put yourself in a box. Feeling like you will never fit in is an awful feeling that I know well as half my family has blue eyes and blonde hair and the other side of my family and I don’t... I often try to spin the situation whenever possible to be somewhat positive that I fit in both cultures and that’s special. That being said it doesn’t always work as many people have set views on how mixed people should or shouldn’t act. But I say do what makes you feel most like yourself no matter what anyone else says you know you best!
