I also have both and it can be very confusing in the beginning, so don't beat yourself up for not knowing everything right now.


To grossly over simplify, for the sake of keeping it concise, my Bp is random, I can wake up fine and fall asleep suicidal or vice versa without any external contributing factors. Also, external factors cannot alter a current mood state.


My bpd is triggered by my environment, people, situations, and how they make me feel and think. So something can make me euphoric, and later something else can make me want to self harm.


In time as you familiarize yourself with your battles, you'll learn to detangle the two.
