That’s tough. To be totally honest with you I have been dealing with negativity in one way or another my whole life. Now I find myself avoiding it as much as possible. I guess you need to ask yourself what you are actually getting out of it? What do you get from being negative? What do you get from chasing to be around negative people or situations or feelings? Usually we are engaged in something because there is a reciprocal relationship happening with that thing. I think once you understand that you can start to be less reactive or less habituated toward negativity. For me negativity was a way of dealing with fears. I still struggle with it today. I think in life sometimes the best thing we can do is to just accept things like negativity as just something that is part of our character and then begin to find ways of managing it. Management is the key to finding serenity i think.
