PTSD from Sexual assaults.

I have been struggling with my PTSD for almost a year now and I am on two therapy sessions and on medication. I am also trying meditation. I am trying everything I can, but sometimes, I get panic attacks or flashbacks. It was manageable in the beggining, but now ita hard to control. Sometimes I cry a lot and get angry a lot as well. If anyone has any tips, please let me know.
