Apparently I have BPD??

I came on here because ACCORDING to my doctors and multiple friends and family I have Borderline. Maybe I'm stereotyping when I say this and please correct me when I am wrong but I feel like I am not a typical case???? I feel like my friends with borderline complain about feeling sad constantly and struggling with commitment. My default emotion is ALWAYS anger, like I feel like if the littlest thing happens I'll instantly get angry not sad, yes when I get sad it gets really big but I'm usually more angry but like 50% of the time I'm both really sad and mad, like I'll be yelling while crying. And ALSO I have no problems with commitment at all, the only problem is I never know when to give up, I will dedicate my whole life to something when I promise I wont give up, even if it's pointless or practically impossible. Yes I can be impulsive but I also like to plan things out, I often plan out for any possible scenario in my head and usually do what I feel is best for me (Sometimes I forget to take other people's emotions into my mind). I have a lot of unstable relationships but I don't know, maybe I'm just weird??? I feel like EVERYBODYYYY is trying to put a label or something on me, but if it's not borderline am I just fucked up and it's all MY fault? if I really do have nothing going on with me, am I just broken? and I do try to get better but sometimes I feel like there's no reason for me to try to and it takes me getting so low to realize it's happening ALLLLL OVER AGAIN. i cycle so much and it makes me so mad that i keep cycling. what do i even DO in this situation??? this is all so unfair and stupid.
