As the emotional part of our brain sees imagination and memory as the same, this resolved the trauma
I think you are talking about something downstream from the problem OP reported. What you said explains why changing the memory would help. But I think it is not relevant to the question of whether you *can* change the memory.
If there are parts of you that think that holding on to the memory and to whatever partial solutions you came up with at the time are important, you will have trouble changing that, no matter what the benefits would be after the fact.
And of course given the traumatic nature of such memories, holding onto them and to the solutions you found do tend to seem very important. Books and reports of therapy are full of examples of this kind of thing.
