PTSD does direct everyone's life, who has it, at least until one learns how it is affecting life and learns how to counter it. For some it takes many, many years. But no matter how much or little control is gained, there is no cure, and often rears it's head to haunt the most seasoned person.
It's like all your memories are no longer neatly filed but instead strewn all over the floor of the filing room! Each time you try to file something, you can't find it's folder, and once you get a few into new folders, the filing cabinet won't open. PTSD causes such resistance to becoming controlled...imo.... it's almost like a chinese finger puzzle. Going more slowly and gently working through the facts of ptsd and working with the known methods for retraining the brain is the best way.
Another thing that PTSD tends to cause, is that of exacerbating any and all of your bad traits. Even those traits that were worked through and "solved" such as an angry spirit or use of foul language, ptsd brings it all right back as though they were never solved in the first place. It is truly a time of knowing better and (seemingly) having no control. Then you add the frustration of that!
