DISOBEYING FATHER FOR NOT DOING HARAM JOB

Asslamualikum! I was a finance student back 2 years ago. You know that doing job in a bank is haram as it involves Interest so due to this reason my aim was to do a job in a company as they aren't indulge in interest. But my father wanted me to do a job in a bank as there was a reference. But I refused from day one due to above mentioned reasons. And got a job in a Cargo company as Data entry specialist. My father become unhappy as so my whole family. Things become more worse when I discover my colleagues having poor and absurd mentality in the company. But still I was happy that I was doing a Halal job. But after 3 months a rider and then my director sales harassed me. Due to which I got Bipolar mental disorder. And I have to be admitted in hospital for 10 days and left job eventually. Now I want to ask you is that was a punishment from Allah not obeying my father as I haven't recovered yet. Whenever I find a new job (after that incident) I got fired after some months. I used to listen that when you avoid haram things and do halal things Allah become happy but I am puzzled on the things happening around me. Please guide me for the sake of Allah I am completely hopeless. Please reply me it would be a great help.
