Is it normal that i might be insecure/unsure about my race?

Er, just tell them that she's Hispanic.

i am half and half too. my mom is from Thailand, but everyone always assumes she's Chinese or Japanese. gotta be proud of your roots!!

Dont let this bother you. people inflict their own pain and perceptions on you... insecurity.

I am mixed too. and I am tired of both groups. black people tend to tell you you are only their race, and if you state u are mix to them, they behave nasty, they can be very prejudice. Also,white people can be prejudiced and racist too, but I feel they have treated me nicer than blacks. But it is half and half. I am tired of both groups. both are lacking. and i do agree it is a power issue.

I think you should be proud of your race. I can understand being confused, but I don't think trying to avoid it is a good thing to do.

FORGET FEELING BADLY ABOUT COLOUR...IT IS SO STUPID...WE ARE ALL HUMANS REGARDLESS.
I AM WHITE, AND SICK AND TIRED OF HEARING HOW GOOD WE WHITES..ARE...WE ARE NO BETTER THAN BLACKS..OR ANYONE ELSE..IT IS JUST A MYTH TO PERPETUATE THE POWER THING.

Unless someone is already very familiar with you, like a friend or a coworker that you get along with well, it's actually impolite for people to ask you that question.

When you are not sure of their motives, instead of explaining the truth to them right away, you could say in a pleasant tone of voice:
"Why do you ask?"
That will give them a pause and they'll maybe reconsider pestering you with those sort of personal questions.

I also think that when you tell people that you are 1/2 Greek and 1/2 Peruvian, they should accept that as the truth and they are just being ignorant if they push you further.

I don't mean you shouldn't be proud of your heritage, but I just think you should be aware that you don't owe people an explanation. [If healthcare professionals ask you, you should tell them because it may help them.]

I'm mixed myself and I'm the kind of mixed where people can tell so I get asked what I'm mixed with all the time. I simply tell them the truth. If people want more of an explanation, I give it to them. They think it's interesting and I think it's fun to tell. If you look at it as a cool thing, a thing that sets you apart and makes you interesting, it can be fun. If it gets tiring to keep explaining just say your half white half Peruvian and if they say but your mom looks black just shrug and be like ' she's Peruvian, they have similar features to black people' which is true. If they act like they don't believe you, tell them to look it up. There are lots of different kinds of Hispanic so they should take your word for it. They're being a bit naive by thinking your mom isn't Hispanic just because she looks black, half of Cuba is of African descent so a lot of them look black too. For your issue of belonging, it can be quite a struggle sometimes for us or at least the ones I talk to. For me, I use to just claim one side because I thought I looked more like it, turns out the people I thought I looked more like are the ones who claim they can tell I'm mixed from a mile away. By the time I was in my teens I just claimed both because I'd always been proud of both. When I felt super confused I just read stuff about my cultures so to at least learn more, that turned out to be a great thing, it made me feel enlightened about my people. So honestly, don’t sweat it, us mixed folk are awesome!
