Borderline personality disorder, short BPD: a pattern of abnormal behavior characterized by the following:
\ unstable relationships with other people
\ unstable sense of self
\ unstable emotions
\ often dangerous behavior and self-harm
\ struggling with a feeling of emptiness and a fear of abandonment

- Symptoms may be brought on by seemingly normal events. (-> emotional overreacting)
- The behavior typically begins by early adulthood, and occurs across a variety of situations.
- Substance abuse, depression, and eating disorders are commonly associated with BPD.
- Females are diagnosed about three times as often as males

Approximately 10% of those with BPD commit suicide.

This article goes to all those who think they might suffer from this or have a loved one who shows this behaviour.
I hope it will help you to understand and treat it better, and also I want to start a conversation about this kind of disorder, since there's still a big stigma around it and most people prefer to stay silent.

How does it show in particular? (I'll take myself as an example.)
You may be unsure and confused about your identity or your morals and values,
which leaves a chaos of muddy thoughts in your head.
You'll be controlled by your emotions rather than your emotions are controlled by you, which leads to impulsivity.
To numb these intense unpleasant feelings many reach for distraction in drugs and basically anything that spikes the endorphins, like overeating or doing risky things like having flings. For many, that's already become a coping mechanism to keep their mood more or less stable.
The other way to deal with it is drowning yourself in those feelings,
for example when someone rejects you, you wallow in self-pity the whole day, listen to sad music and cry everytime you think about the words this person said to you. And since BPDs tend to be overthinkers as well, you'll probably analyze the reason for it, and most times you will come to the conclusion that it's all your fault. And if your mood wasn't good to beginn with, you'll probably fall in the pit of self-loathing and hating everything about you and the world in general.
I've noticed that people with BPD are outstandingly artistic, which is probably because they use art to process their emotions.

"The sensitivity and intensity with which people with BPD feel emotions can have both, positive and negative effects: People with BPD are often exceptionally enthusiastic, idealistic, joyful, and loving. However, they may feel overwhelmed by negative emotions (like anxiety, depression, shame, worry, anger), experiencing intense grief instead of sadness, shame and humiliation instead of mild embarrassment, rage instead of annoyance, and panic instead of nervousness."

This was only 1/10 of what I wanted to share with you,
I hope I get to write about this soon again.
I anyone can relate to this or you are concerned about someone else, feel free to message me and I'll try my best to help.
