I had undiagnosed bipolar for as long as I can remember, though I don't agree with labeling and medicating a child for it with what is available now. I understand the anger kathleen is talking about, for the same reasons.

My answer to your question would be that yes, I would wish to forget those memories because they are serving no useful purpose to me on my journey at present. My goal is inner peace and staying in the moment. Those memories are exactly what created negative pathways in my mind, and forgetting them would make my goal far easier to achieve.
