Question about Wise Mind

hello, i've recently printed this emotion regulation worksheet. the word "wise mind" and "emotion mind" come up often.

for refrence i am not diagnosed with BPD, but i've had the crippling suspicion all my life. currently trying to find a free therapist through university because i don't have the money.

anyway, the way i've always explained to people the way i feel is that i have a "rational part" that knows what's right and what's not, it knows that what i feel is not real, most of the time is paranoia, or rumination, or self loathing, or self sabotaging; on the other side though is my "emotional part" that feels all the made-up things in my head are real, sometimes it overpowers the "rational side". it's like they are two simultaneous trains of thought, happening at the same time, which is very tiring.

my question is, have i been accidentally refrencing "wise mind" and "emotion mind" all my life without even knowing they were real terms for this disorder?
