My mood jumps from severe depression, and intense anxiety, to anger to... this weird emotion I’ve only been describing as anger? But it’s not?

Its like a mixture of anger, and being fed up. But also like just an intense urge to let everything go and just be a bad person. Idk it’s an urge to be a bad person. I have no idea how to explain it more, but I’d like to know if this is a part of BPD or not :)
