Why my family raise fingers at me for no mistake !?

I understand your use of the third person. This is an incredibly sad situation. I am not sure what you must do to survive with your self esteem intact. The most simple idea I can think of is to develop a mantra to repeat. "I am a valuable person." Find something that you are good at, I know you can type on the computer, so you have some skills. Use your education to advance your position in life to the best of your ability. Avoid trouble and mind your own business.
