Need help or push for right direction.

Dear Dr, My name is Aditya Kadam. I am an engineer & working in private company..I have wasted few years in study & had some bad years. Our family has gone through lot of tough periods in past 2 years. I am also in a relationship & we both want to marry each other. She is 26 & her parents are searching bridegroom for her,which is fair from their perspective. My family consists of My mother who is 50 a housewife. Father,61 who is retired. & my younger sister,19 who is in T.Y.B.A&F. 2 yrs ago,when my father retired,he had financial loss,debts,etc. He sold our house for paying the debts. Right now we are living by rent. My girl has helped me alot in these period. I couldnt tell to my parents about her as our families wont accept our relation. At this point of my career,I couldn't decide which job profession will be best suitable for me so that I could have good future with it & also look up to my people. I know its been very long query & hard to understand at first,but I really need help.
