You are being abused by your family.
If you're under 18, you're child abuse.
Please consult with child counseling centers, etc.
Among those who have been abused, there are people with little sense of self-affirmation that they think they have no value.
It is an “illusion” and “misunderstanding” that people have assumed due to abuse.
If you don't use the rationale of “I'm being abused because I have no value,” you may think so because you won't be convinced.
However, the facts are different.
It's not because you have no value,
It's simply that your family members are stupid (less capable) and bad people.
For example, if your family and parents are geniuses like the Buddha, they will take care of you with a smile without getting angry, no matter how difficult the child is.
However, when the parent's ability is low, they are unable to take care of the child in a cool way (their abilities are poor), so the parents themselves are panicked, upset, and angry.
Do you understand?
People who get angry and commit violence are stupid, so their ability to process their head and mind can't keep up, and they panic.
You're panicking not because you're worthless, just because your family is stupid.
Please consult with a proper third party.
If necessary, they may be able to protect themselves and hide in a safe place.
Maybe it's a good idea to get away from your family.
