Please forgive your mother

I am sorry to hear your traumatic experience during childhood.  It is very difficult to get over the negative experience, but not your fault.  May consider seeing a counselor for helping get over this  negative impact.  At the same time,  it is unfair to blame your mother for your traumatic experience. I agree telling your mother probably won't help the situation but to make her guilty. My mom blamed me when my period was earlier than her. Sorry I don't know how to type chinese in the computer and hope it helps.
