Helplessness. Thing i like is work now.

I am 31 yrs old engineer. I am married and due to unavoidable situation I am feeling like I am exhausting my life each and everyday. I have 8 month old son and my wife always unhappy with the fact that the baby was unplanned. My wife is working professional and she has very bad relationship with my parents. My parents are very much selfish and I mean it. They only care about themselves, threw me out of house, Now my father is diagnosed with cancer being a single child I have to do all the required work due to that my career is at stake. I cant stay with my family and my in-laws also behave very badly with me. Only thing they valued is money. I do not have home or car and cant lead luxurious life though I earn 55000 per month. All facilities they took from me, from baby seater to responsible child. Disrespectful behaviour towards me is always present. You wont believe my mother think that I will still my father's money due to my financial situation. only thing I like is work now.
