Thats the problem though, therapists won't dig at you too much because of legal liability nowadays... being you walk out the door, commit suicide, someone is going to begin asking questions basically. Suicide is something you must control for starters, being you must come to terms with putting that shit out of your head, or simply go and do it if that is what you want. Either way, if you want to die, nothing anyone says will stop you except for you. That is the first decision to have to consciously make and stick by regardless how shit you feel, or are going to feel during the healing process.
If you come to me telling me that you want to commit suicide, and you didn't want to make an active decision to ensure you don't, being you really don't want to die and regardless what your brain tells you, you will fight it and not do the act, then I wouldn't touch you either, because your simply too much of a risk to yourself. I would simply tell you to go away, when you sort yourself out mentally in that regard, then come back and see me.
If you think what you have done thus far is tough, your only scratching the surface at a rough guess for when you really are provoked in relation to your trauma. Touchy feelie... soft approach DOES NOT work for PTSD.
