Other People’s Drama

I’m tired of dealing with other people’s drama and negativity.  They keep coming to me with their problems and in the past I have normally entertained their drama but now I seem to be having a hard time holding space for their problems and their desire to wallow.  I don’t know how to stop this behavior in the best way because right now my thought is I want them to go away with their drama which makes me angry and frustrated and I avoid contact with them.
