A boy of 18 years old is not taken care of by his parents at home, or even abandoned. what should he do ？

You are a good cousin, but if you want to help him, you have to rely on you, because you are the only person he can talk to. Now answer your three questions.

1. You should talk to him more and tell him that life is beautiful, but you need to try to tell him that he is not alone, and there are many people around him who care about him. Let him learn to face the society and change himself.

As for his family relationship, you should let him know the pains of his parents. They also hate iron not to produce, and they all think of him. If you want to change the current family relationship, you should enlighten him more, let him change, overcome his rebellious psychology and let him learn to understand his parents.

If he really goes on like this, he won't be distorted. He feels a little schizophrenic now.

I suggest you take him to consult a psychologist. I wish you success!
