Um no, hate to say it but your T is wrong on this one. Human memory has this way of remembering poignant moments in time weather good or bad. However as humans we remember the bad and that is what stays with us much longer than the good. This is actually normal to remember the bad and not the good. Yes, when some abuse is so horrible people do block it out, but often times they then have little to no memory at all. No good or bad, just nothing. Most people can tell you some good stories, about their first kindergarten play or a special birthday party as a child, but there are not a lot of positive memories we as humans hold onto. We hold to the bad because it is what disturbs us and we keep thinking about it and so it becomes implanted into longer term memory. This is not the case when someone represses something, but normally, we remember the negative comment someone said to us and completely forget that three other people said something positive. Because it is that one negative that hurts. This applies to all situations including abuse, as I said with the exception of repression. so perhaps your T expects people to repress their painful memories, but not everyone does. You can do some research on memory though and bring it to your T if you want to show her the way memory actually works in regard to positive vs. negative events, and how people experience them. Good luck! and blessings.
