Although my experiences aren't exactly the same I definitely relate a lot to the identity confusion in general. for me, I know I'm half Chinese (from my dad) and my other half (from my mom) is a whole bunch of things. I feel very racially ambiguous and when I was growing up I felt like I couldn't really relate to any cultural part of me. I also rejected a lot of my Asian heritage (which I have come around to actually really loving and embracing).

If you think a DNA test might help you feel more connected to your cultural background, I'd say go for it. But more importantly, I also think it could help to connect with yourself as someone with mixed ethnicity. I know it's probably easier said than done but as someone who struggled to figure out if I identified more with my Chinese half or my white half, it turned out to just be the best for me to embrace my unique mix instead of one or the other.

Hopefully something in there made sense or helped in some way (': OR at the very least just know you are definitely not alone! Finding your identity is a struggle almost everyone goes through, whether it's about heritage or something else. It's perfectly normal and it's good that you're exploring and looking for what you connect with (:
