I need some help. I need something.

The majority of every day I have images in my head. They're usually violent and play out really screwed up. I don't want any of this. I get urges to follow through when it comes to the SH related ones, but every time I give in it's never how it is in my head and therefore not right. Which leads me to needing to do more. The other stuff is violence towards others, like killing my mom, and I don't want to do it. I really don't want to. My pdoc says I don't have to follow through on these thoughts, but they're not just thoughts. Thoughts leave, these don't, they just get worse. I have a voice in my head telling me how to do it and he won't shut up. I've been told that this is an outcome of my PTSD and nothing else. How the **** that is, I don't know.

Does anyone have any tips for dealing with this? Mindfulness only helps me so much.
