what you said about blocking out the memories resonates with me. i have done the same to the extent that i cant remember my childhood any further back than when i was about 17. i also have a compulsion to throw out anything to do with memories, i have no photos of myself or my family, with the exception of some photos of my 2 young children i feel too guilty to not keep those. my therapist was concerned this repression was due to some abuse but i doubt it, i think its just my way of blocking out all my awkward moments and continuous failures to be a normal member of society.
