How to deal with harassment from mother

Respected Sir, I am . With due respect i beg to state that I work as a receptionist in Sanjeevani Hospital. My father is a mechanic and my mother is a house wife. I belong to a needy family. I contribute as much as possible to the daily expenses of our family. Now a days my mother threats me to get married without my allowance and she behaves and tortures me in an inhuman way . She ill-treats me verbally and mentally and i am forced to commit suicide despite knowing that suicide is not a solution.My father is just a mere spectator of the situation. In this circumstance,I beg of you to please show me a proper way to deal with this problem.Being much helpless i have to write such words about my mother.I look forward for your help as my last hope. Thanking you in advance, Yours truly
