An illness where a person acts in an edgy manor for attention, manipulates and forces people to feel guilty for them. Has a habit of self-diagnosing OR if they are diagnosed they will bring it up whenever they get the chance to. They have a "tragic backstory" they will share with any new friend, twisted morals and often threatens people about killing themselves if they don't get their will. They are "always" the victim, and if the conversation isn't about them they will do whatever they can to divert the attention to themselves and their problems. If someone attempt to help them with their so-called mental illness, they'll make as many excuses as they can, as well as disregard any advice and reassurance.
"Ugh, I tried having a conversation but they have such a bad case of bam syndrome that it became all about their mental state"
