Do i have borderline personality disorder?

ok this is hard to explain and if you dont experiance this then youre going to think im crazy. But i act diffrent with diffrent people like i feel diffrent with diffrent people. Its not like if im talking to my parents(i talk to my mom my dads a deadbeat but i talk to her how i talk to my friends and drink with her lol shes chill as ****) but what i mean is i see how that person views me like i think of how he thinks of me wether its me being funny,smart,stupid, like i have minor social anxiety and its diffrent with diffrent people im completly myself around my mom my close friends and my girlfirend but if i talk to someone who is like a "gangsta" like i feel so white and i feel like he thinks im a typical whiteboy(wich im not im more like a black person i listen to rap, dont have a father, ****** up childhood, smoke weed errddayyy lol,) sorry if your offended im not racist i have more black friends than anything else. but i just feel like a diffrent person like im being shy and showing a shy stupid version of me lol thats the best way too put it. And then ill try to act cool around other people like jocks, girls when i didnt have a girlfirend, little kids, i kind of show off. Idk what this is i wish i could be myslef the whole day im thinking its social anxiety if anybody has any input or knowledge about this pleas help.
