family issues

im not sure if this is the right category but i dont know where else to post this and sorry if it's too long but i really need opinions. i go to college in america (my parents live in greece) and i've been living with a friend from hs (totally on our own savings-we don't get any sort of financial help from our families) in brooklyn. the thing is that my family gives me serious anxiety since i was 8 or 9 and it's not just academic pressure. i'm pretty introverted, and they get mad when i don't tell them about my life. they used to do it back in greece, and it hasnt changed since i got in ny. most of my dialogues with my mom or my dad end with me crying in the bathroom without them knowing, which makes me drift even further away from them. i dont like visiting or spending time with them but they get mad and assume things (such as i'm a drug addict) when i dont. i really dont wanna have them in my life but i dont know what to do. i really need your advice
