Yes cynp , you could be right.
People with borderline personality disorder (BPD) often have lower baseline levels of endorphins, which can lead to chronic dysphoria and an intense, often unconscious, drive to stimulate their own opioid system. Here is some research on that:
The alarming symptoms and self-destructive behaviors of the affected patients may be explained by uncontrollable and unconscious attempts to stimulate their endogenous opioid system (EOS) and the dopaminergic reward system, regardless of the possible harmful consequences.
Frantic efforts to avoid abandonment, frequent and risky sexual contacts, and attention-seeking behavior may be explained by attempts to make use of the rewarding effects of human attachment mediated by the EOS.
Self-injury, food restriction, aggressive behavior, and sensation seeking may be interpreted as desperate attempts to artificially set the body to survival mode in order to mobilize the last reserves of the EOS.
BPD-associated symptoms, such as substance abuse, anorexia, self-injury, depersonalization, and sexual overstimulation, can be treated successfully with opioid receptor antagonists.

Now the link between anger and addiction:
Anger can be an empowering and therapeutic emotion when released in a healthy way, but it can also be addictive. Just like individuals who seek thrills for the adrenaline rush, some people have the same effect from anger. Individuals can become addicted to endorphins they feel when they get angry.
