False memories?

Hi,

I'm currently dealing a lot with childhood memories, for which I now have an answer. I also had a memory that, in retrospect, turned out to be true, even though I was unsure about the memory. Now, however, I have another one that I can imagine happened, but it doesn't feel real either. However, this memory feels exactly like the one that turned out to be true. Do you know if there's anything that can be done (a therapist, etc.)? These are all very serious memories, which is why I'm really interested in finding answers to them.
