HI i amtwilight,
I think that things keep coming back until they are fully processed by us - do you know what the trigger was? Are you speaking with a psychologist or psychiatrist? a psyche nurse can only do so much and they only have limited knowledge so they can only help to a degree - I know that things only started to settle when I got talking to a psychologist who could help me make sense of it all (well some of it!)
I am glad you are grounded and that you got through this - give yourself a pat on the back
