I am very thankful for those who are able to do as you in "forgetting" your past.
I wouldn't term it forgetting. I don't think it's even possible to actually forget anything. May be more of how we dictate/govern/throttle with our active mind over our subconscious memory bank i.e. how it's ruled. There is an incredibly massive storehouse of data in our minds including a flood of various emotional input as well. If we think of all the data that we take in, all the thoughts and emotions we've ever had, that is all stored somewhere in the wetware. IF it's not governed it would immobilize us. There can be serious struggles with that engagement.
My wife is able to do even better in that she absolutely cannot consciously recall her abuse except in vaguely. I thought I had done a very good job myself until I hit my 40s. Then it started bubbling out of my subconscious mind until it just flooded out. Now there are still pieces that are still lodged back there that come loose to find their place in the giant jigsaw puzzle of my life. Once the memory activates, I feel I must find its place so I can digest it or process it until it takes its place and I can say .....OK.
I hear ya. Sometimes we have to say it wasn't OK but it did happen. Seal chapter. Most of us have to, by nature of being able to function, operate with various caps/lids/covers on ourselves. The abuses happened. But a flood or emotional reactions against it can still trouble the active thought stream.
I think those who processed their memories early on found some way to cope......I chose to run away from mine.....I think that was a mistake.
There are other factors that begin to weigh in with age as well. A lot of older folk get very introspective about their lives and spend a lot of time in regrets, second guessing or heavy analysis of the data.
Sometimes just staying in now, keeping it simple and looking forward is preferable. What went on is done. It can't be changed, nor can the emotions had at the time be altered, nor can the regrets and second guessing.
Faith and the arena's that faith engages is very helpful. Understanding mercy, grace, forgiveness, love are great tools in these regards. Comforting and stilling the mind and heart. Turning our faces in that direction, exposing ourselves to Him, putting His Light and Wisdom upon things. Trusting. Internal peace making.
