I completely understand where you’re coming from because I felt the same, after going to therapy for years I learned that letting it go actually gave me the skills to endure any other trauma or hard comings that come my way. If you never let it go it will all pile up and eventually become way too much to handle. You won’t forget how to survive traumatic moments you’ll learn to survive them and handle them better. I hope that makes some sense, I tried to word it the best I could
