Hello Magen,
First of all, what is your situation? Have you been diagnosed with PTSD? Are you undergoing any form of treatment? It sounds like you have issues that need confronting and dealing with, so I hope you're receiving professional help to do that.
As a supporter of someone who has frequently displayed nasty behaviour to me, it would be interesting to hear more from a sufferer's viewpoint, to gain insight into what is going through your minds at the time when you're lashing out. Fear? Anger? Frustration? I would love to hear more of your story.
Why don't you re-post this as a new thread rather than tagging it on the end of this one. Just a thought.
Hope you find as much help and support here as I have. :hug:
