I'm the other way around, I can get a bit weird (for lack of a better term) during certain dates (battle dates like the Somme, Vimy, Normandy etc) that trigger heavy flashbacks or I'm down for no reason
Then doing a regression actually helps me find the reason why I am that way
The other day my right arm was painfull and wasn't related to the fracture I had as a kid and did a walk through and turned out that the pain came from a sprain received after a poor landing during the start of Market Garden where my chute and medic bag got tangled upon landing (I can cautiously tap into my PLs without doing a full regression these days)
After a regression I usually feel calm and can put that PL to bed for a little while, even when it comes to the part of how I died
But my soul has never known peace, all my earliest memories that I can recall relate to any of my PLs and have always been of war, but I can inmagine that for those peacefull souls (to give it a name) seeing a violent part of your past can be really upsetting
Perhaps an idea of working with someone trained in regression to uncover happy memories? Not everything was bad and traumatic, even I can tap into a few happy memories to balance the bad ones
That being said, you do need to adress those traumatic events, as hard and difficult as they are, because that's why you get those memories first/the most, to resolve them and get closure
