Self-harm comes in many forms. Usually, not even the person who is harming themselves knows why they do what they do.This is because it is a subconscious impulse coming from deep inside. Sometimes it is in the form of self-sabotage that causes emotional, interpersonal, academic/occupational, and/or financial consequences. Cutting, burning, or otherwise physically wounding ones self is even harder to understand. What motivates someone to deliberately, physically harm themselves?
Before we look at a few of the more typical reasons self-harm is acted-out, let me point out that there are about as many descriptions for the experience as there are people who have, or are, injuring themselves.
This is because they themselves frequently don't often know why they do it -- so they come up with their own way of trying to explain it.
Many people who harm themselves usually ask the same questions as those who love them and want to understand why.
The major difference is that the person who self-harms has a lot of shame about it.
The most often identified motivations for self-harm include but are not limited to the following:
Acting-Out Abandonment, Shame & Contempt
All of the above behaviors are frequently bi-products of the Abandonment, Shame, and Contempt described in the Iceberg Presentation. Below is a diagram of a pathway that leads from the original pain of abandonment (Trauma) to harmful coping and/or healthy coping:

Moving upward on the diagram, a "Trigger" is anything that reminds the victim of the Original Trauma -- see pattern-matching if you want to learn more about "triggers".
"Trauma Echoes" are the result of the trigger -- a "flashback" or re-experiencing of the Original Trauma occurs at some level of intensity (mild/moderate/severe). Often times only parts of the repressed material surfaces, usually only the feelings with no images or experiences to tie the feelings to.
A split second after the "trauma echo" occurs the subconscious mind is at a behavioral "Choice Point" -- It can choose healthy coping, or it can choose some form of distraction -- usually in the form of behavior that is harmful to self or others.
Externalizers usually unconsciously "choose" behaviors that are harmful to others, such as emotional, physical, or even sexual abuse. Internalizers turn their contempt inward, distracting themselves through self-harm behaviors such as emotional, physical, or even sexual abuse (e.g., promiscuity).
In order to bypass the harmful coping behaviors and proceed strait to healthy coping one must learn the four basic skills of the acronym R.A.K.E..
The "Iceberg", Part I -- Abandonment
The "Iceberg", Part II -- Codependency
The "Iceberg", Part III -- Addictive Personality
The "Iceberg", Part IV -- Overcoming Addiction
