What are the more common mental diseases?

The main feature of mental illness is that it can't distinguish boundaries. Therefore, mental illness can be divided into three categories: indistinguishable physical boundary, indistinguishable emotional boundary, indistinguishable personality boundary.

For example, bipolar manic depression belongs to the category of indistinguishable emotional boundaries, which may be caused by physical pain. However, this person may be paranoid about happiness and refuse to be sad, so pain and sadness cannot pass through this person's body smoothly, so this person's mood will be confused, because they are suppressed, and when they rebound, they will be confused. Once they are confused, manic will appear After mania, there must be depression, which is bipolar manic depression.

It's obvious that people can't distinguish the boundary of their bodies. For example, sexual assault is a very typical one. There is a boundary between other people's bodies and their own bodies, which can't be touched without permission. Therefore, sexual assault must be a mental attack. He takes other people's bodies as a part of himself. Another common one is obesity. The essence of obesity is actually to invade Taking up more space also belongs to unclear body boundary, which is more restrained than sexual assault, but it is also a kind of encroachment, because obesity is a kind of self mutilation, which belongs to the category of mental illness that can't distinguish body boundary whether it's infringing others' body or one's own body.

It's hard to distinguish the boundary of personality, such as dual personality or multiple personality. This kind of people often have a very serious delusion of being killed. This kind of people are very concerned about themselves and are very afraid of being killed. The purpose of multiple personality is to protect themselves, but in fact, it is counterproductive. When people see such strange people, they will attack them more, because people will attack them out of fear, not because of fear You are weak and attack you. There are two reasons to attack you. One is insecurity, and the other is psychotic attack. No one will attack the other because the other is weak. If people will attack the other because the other is weak, then the ants in the world should be extinct. In fact, they don't, so the reason to be attacked is absolutely not because you are weak, so there are many reasons There is no need to attach importance to personality.
