I got 2 questions about learning a new language

Hello guys! I wanna ask two questions that I've had for a while which is

1. Does my native language affect my language learning ability?
   
2. How do I get over my fear of learning a new language?

A bit of background, I speak two languages at home, mandarin and hokkien both I consider my native and heritage respectively, while I'm outside of home I mostly use mandarin and english due to english being the working language and mandarin being the lingua franca of the chinese community here. I have this fear of learning a foreign language especially a european one due to my past experience being mocked for it and being named as "Trying abandon/reject my roots" or "being a western worshipper (real thing that I've been called)"

Now the language that I wanna learn which is russian is well.. very controversial due to what's happening in the world. Me wanting to learn russian is due to the john wick films and from a game called metro exodus which takes place in a post-apocalyptic russia
