“I can't master my nerves and I cry for any reason. I am angry with myself because of this, I hate myself and I'm ready to do something about this anger. I envy the girls, who can admonish their own and have no problems like me. How do I fight this terrible weakness?”
You probably can't express your anger. You were probably brought up in the belief, that polite girls should not get angry. But emotions accumulate in every person and at some point they must find some outlet.
In your case it is crying. This is not the best solution for an adult woman. I suggest exercising anger. Please try to start with, standing in front of the mirror, shout, what bothers you. If the attempt fails, I advise you to contact a psychologist.
