lindsey,

I can understand replaying and regretting what has happened.  There is a therapy I read about that can supplement seeing an in person therapsit that deals with trauma (among other things).  There is traditional journaling which there are articles that guide you.  There is also another approach where you re-write your life.  It is journaling in a way but you write your own story.  It helps you take control of your life again.

I’m looking at TRE, Trauma Release Exercises for myself.  It’s appealing for I won’t need a counselor/therapist beyond that I need to learn it in order to practice it for myself.  It also is taught by other practitioners like yoga instructors.

There are a myriad of other modalities that help PTSD like EMDR, EFT, and others.

Right now, try journaling as the first step.  Look up ways on how best approach that.
