New errand for me

I was fully running a new errand since today. The ex manager has left the company, and I was confronted with the internal turmoil on those few days before she leave. The close friends and dearest have the complete details about the happening. I'm not the one to be accused for this issue. But I have the contrary circumstances now, one or two of the coworkers keep the bad side of me (which was spread by the ex manager to all the community).
I keep telling myself tat I'm working for myself, not working for making the coworkers happy with me.
