To My Loved Ones:

I am writing this letter to help you understand what those of us with borderline personality disorder (BPD) go through. It is a severe mental illness, and yet describing it is often very difficult to put into words.

Studies have shown that people diagnosed with BPD actually have brains that differ from that of the general population. The part of our brain that deals with emotional responses is overactive, meaning that we are highly sensitive and our emotions are extremely intense and unstable. The prefrontal cortex is the part of the brain that is responsible for reasoning and logic. It is this part of the brain that will stop people from behaving in a certain way due to consequences. In those of us with BPD, this part of our brain is underactive—meaning we are unable to think rationally and often act out without thinking of the consequences.

I feel this is important to tell you, as so many people are misinformed regarding this disorder, with a few questioning whether BPD is even a thing, due to the fact that you cannot “see” our mental health. If you were to see inside our brain, however, you would realize that BPD is there.
