Is it a common thing to aggressively "lawyer" other people when they present an argument or something that potentially leaves you to blame? And I don't mean /intentionally twisting/ something to NOT be your fault; I mean its either a) not at all your fault or b) potentially up in the air who is to blame. 

I find that on days I forgot my meds, haven't slept well, or eaten... I tend to be more aggressive with my defending myself. I often find that outside of arguments, I latch on to words and situations that may be deemed as important or evidence to defend me should the situation arise. 

I mainly think this cuz I was submissive growing up and pretty much took the blame for everything.... but as I grew older I got sick of nkt defending myself and speaking up..... but now I think I may be too aggressive about it. Is this potentially part of BPD?
