I had them for quite a number of years when I was in my early 20s.
Brought in by a change in my lifestyle, location in the world and time to reflect on my past life.
Mostly brought in when I was quite relaxed, riding motorbikes, or bicycles, other times from what I suppose would be called flashbacks.
I learnt to recognise what they were first. That knotted feeling in my stomach, the usually rational thoughts now jumping all-over the place, pulse racing my mind screaming to let me get off the ride.
I suppose I self counselled myself, I learned to become reflective, I wasn’t in a country with decent mental health care not could I afford it.
I had to cut some of the triggers out,.My love of jungle and drum nbass had to be stopped for nearly 10 years.
I was fortunate to be away from the lifestyle and influences that got me there so that was in.my favour.
I still have moments where things flash into my mind, quite often “how didn’t I die from that” and I can feel it rising up a bit, but I can usually push it back down and get on with things.
Probably not much help
