Lost a Friend and Feeling Betrayed

So it’s been awhile since I made a post and I honestly need to make one. I lost one of my best friends due to having to leave the apartment that we shared because my hours got cut back. She spread rumors about me that weren’t true and now I lost more friends because of it. She’s making me look like the bad guy and every person I went to to vent about it has screenshotted what I said and sent it to her which made the situation worse. I’m at my lowest point right now and idk what to do I just want it all to stop. Am I in the wrong for talking about the situation to others because I feel like it was better to just keep my feelings in and just let her do whatever she wanted to do and lie about what happened
