Imposter syndrome about ethnic identity

Okay so some background. My dad is a white guy from New York and my mom is Puerto Rican grew up her whole life on the island but also Americanized due to having gone to college in the states. I am very proud of my mom’s culture and it plays a huge role on my interest. The one issue is I don’t really look like a stereotypical Puerto Rican and most of the Spanish that I learned was at school and through studying abroad. Due to these circumstances I feel a lot of imposter syndrome when it comes to my identity as a half Puerto Rican. Sometimes I feel like I need to tone down the pride in my identity because I worry that people will think I’m like one of those white people who say that they are 1% Cherokee 😭. I’m just curious to hear about other people’s experiences with this.
