Well definitely go with whatever topic feels right to you. But one suggestion I can throw out there, is to think of something your mother once said to you, that has lodged itself in your memory. Consider the message she was conveying to you, and how you might have internalized it. Maybe consider using EMDR to challenge that message in some way. The reason I throw out this suggestion, is because I think a lot of people forget (naturally, though) how we perceived things as children. It can be very different from how we perceive things as adults. Internalized messages might sound 'silly' or something as adults, but as children, those messages can carry a lot of weight. Like as an example from myself, my mother once said to me when I was young, "Maybe you're not as smart as you think you are," in a very condescending tone with a smirk on her face. If someone said that to me as an adult, I would probably be like.. okay, good luck with your laughably lame insults, pal. But, I think it was quite different for me when I was young, and especially coming from my mother. It is probably no coincidence that I can be a bit of a covert cerebral narcissist at times. So again just something to consider.
