There really isn't an easy ride when dealing with old trauma unfortunately. Growing up, without support to deal with traumas, you just kind of stuff them down and figure out the best way to get on with things. Which works sometimes and sometimes doesn't. To actually deal with the traumas and their effects you have to take them out and really look at them and that means feeling painful stuff and thinking about painful stuff you have tried to avoid for most of your life.
It definitely hurts more than not looking at it, but it can lead to processing it effectively and truly integrating so that you don't have to spend the rest of your life avoiding stuffing pretending suppressing or dealing with it bursting through and smacking you in the face whenever it gets triggered up.
It is hard but if done right it will be worth it.
