Bi-polar can be very bad, yes, but my guardian had/has BPD and living with that was much, much worse. It really was like walking on eggshells to be around her 99% of the time. I can’t imagine what it must have been like for her and my uncle who has it, Christ. She was diagnosed years after I moved out, unfortunately, as the concept of BPD was very, very new in my youth.
At least with bi-polar disorder, which one of my uni roommates had, you could tell when something was going in one direction or the other, the general mood was sustained for more than a few days, and you could see the pendulum come back around. Plus, she could and did get meds for it in those days.
