deeply hurt and need help

I did a surgery 2 two months, it was really terrible and I was hurt. My live was ruined and changed so much. The situation was 100000 times worse than before. I want to sue the doctor. But when I go to some other specialists, they all keep quiet and did not write anything in their reports, they knew the doctor who did the surgery to me.It was really unfair to me. Please give me some advise what I should do. I am really deeply sad.Please help.
