i see a lot of debate on if mania is a symptom. i believe it's more widely understood that mania is not a symptom of bpd. please if you guys could link me to sites and articles of this that would be great. please do not source health blogs, only reputable sites that are fact checked and down by doctor/psychiatrists.

that would be very appreciated, trying to get more info on it, so far i've found a lot of "he said she said they said" sort of thing in groups and such. 

please link the sites in the comments, if it could distinctly say that mania is NOT a symptom of BPD, instead of what i've found so far which is stuff like "mania is __" "bipolar people have mania, BPD have mood swings" etc. like something that specifically says that our mood swing highs can not be mania.
