How can a symptom be "wrong"? It can't. Self harming behavior is a symptom of something else. It's a coping mechanism, albeit not a good one. Once you resolve the real issue, or find better ways to cope while you work on that other issue, self harm will become less needful, and less effective as well. If you must self harm, do so as safely as possible: self care in the process may seem like an oxymoron, but it's necessary. Generally self harming behavior is not about wanting to die or get really sick, but to feel better.
