Could be both?
Comorbid disorders do exist, ie my Dx is Cyclo and bpd. I dunno bout the Cyclo Dx as I def HAVE had at least 1 MDD actually think I've had about 4 or 5 since I got Ill I'd say I was BP II but hey I'm not the psych.
Can tell the difference between each Dx too.
Depression and Hypo hit with no triggers whereas Bpd does. Sensitivity to emotional stimuli.
Some experts argue that bpd is in fact a manic depressive illness anyway.
I dunno, all I know is I'm f@#'d in the head lol
Can't live without meds, tried and failed epically.
Meds treatment is pretty much the same for both
Therapy differs tho x
