Career fall and lost love.

Have been working in IT for the last 3 years. Started off great. Had horrible work life balance issues but pay-check was good for someone who started their career. Had money to live my life my way for a fresher. But last year, I had a career fall. That led to reduction of salary by double. Understood that the worst thing someone you loved for the longest can tell you is not that they don’t love you back. I have never tried to explain my situation to people. I’m someone with good intelligence and getting a better job is just easy for me because I just have to put efforts. But I don’t know how to explain but I am unable to do that. I see no point in efforts now. I was motivated highly in career and had big plans. But it was just someone’s decision or a bad system that led to a decrement in my salary. Life feels having no purpose. I felt so drained trying hard in my career and past relationship. When I see someone doing things excellent in career, I feel pain. But I remember all those episodes of times where I was beaten down. I then think I would have been like them if I didn’t have this bad past. I’m trying to get over my past but I just cannot do it. Then I remind me that if someone meets with an accident, it might take time to recover physically. Similarly, I met with an emotionally disturbing accident I wasn’t prepared for and that needs time to recover and I don’t have to feel guilty for not doing anything to grow. All my years I did things for growth. Now, it’s not because I’m lazy, but I feel so exhausted trying. At the same time I don’t want to have my future going bad because I didn’t take actions. Not comfortable to openly talk my problems with people I know close.
