People talk about me behind my back?

You have to understand if people are talking about you then they don't have to deal with there own stuff. It is much easier to focus on someone else than to take care of your own backyard. A lot of people are like that but it sounds like you get frustrated and give them more ammunition to use against you. I know it is hard when you are in the moment and are upset not to react but you sound like I was when I was younger. You don't like it when you have an injustice happen so you speak up about it. It often got me in trouble and it may you. I know it is hard but sometimes you just need to walk away. Good luck I hope things get much better for you.
