I recently went through an extremely traumatic event and now all my mental health issues are so much worse. I'm having horrible thoughts that I can't get rid of. I can't stop thinking about suicide, but I don't want to die. I just want to forget what happened, but I can't stop reliving it in horrible vivid details. I have the worst moments of my life or my own death to think about and I can't seem to stop the thoughts. Any advice on getting rid of thoughts that I don't want but can't seem to get out of my head? 

I've tried reading, talking to others, and watching TV but I can't focus on anything and mind inevitably returns to the horrible things.
