I'm 5"1 and 113 lbs..is that too skinny? According to my mom, I'm dying?

My mom and EVERY latino/hispanic person I know who isn't born in the USA are telling me that I'm getting too skinny. Being mexican, our culture thinks eating meat is the way to go! I have made the choice of becoming a pescitarian (mostly vegetarian) and ppl are mis interpreting that as me being anorexic. Caucasian people on the other hand are telling me I look great! But my family is making me feel like Nicole Richie in her disgustingly skinny days. I dont know what to do..I like the way i look. But my family's opinion matters too. My bf LOVES the way I look right now...and I wanna keep going .
