Should I Get Diagnosed with BPD?

i haven’t been diagnosed with bpd but i have friends who have it & say i do. should i look into getting a diagnosis? i’m really impulsive, black & white/all or nothing thinking, horrible self hatred & body image issues, used to self harm, eating disorders, awful anxiety, if anything goes wrong i can’t stand it and lose it which usually results in me feeling overwhelmed & like i want to hurt myself/off myself. when people talk/text with me & they’re not talking/texting like they normally do i think they’re mad at me and my friends say that could also be a sign? when i have a breakdown it feels like the the worst thing ever and sometimes within at the least 45 mins, i feel ridiculous and stupid for feeling like that and then im okay. i say sorry a lot. there’s so much more i’ve had people call me out on but im actually quite scared of a diagnosis. please help.
