I am very concerned about my self-respect.but my family & other relatives take it as my ego. My father is an egoist.He is too bz with fb & politics.He doesnt give family the quality tym ,love ,care & respect.He doesnt even earn.He loves flattery ppl.He hates me because of my harsh reality based talks.On rebelling,he beats me.He wants everything acc to him.He has lost contact with his mother & 6 brothers. My mother is a housewife.She doesnt speak against wrong as she fears of quarrels.My father uses this weakness to the great extent.She is a big flatter. My elder sis does job in noida.She is selfish & doesnt support in any way-neither financially nor morally. My fiance is too an egoist like my father.I fear that he will torture my children the same way as my father did.I am unhappy with him.He has sneezed all my freedom. YES...I too have demerits.But yet I am a positive person.I am schizophrenic patient.I get hyper sometimes.but...IT IS THEM WHO MAKE ME TO REACT IN HYPER WAY...Guide me
