My memory haunts me, and it's almost only bad stuff. I can't get any of the negativity out, permanently, and sometimes it all hits me at once, overwhelming me with thoughts of the reality of this world, and hatred towards the human species. There are only two things I believe could help me, other than true love, of course... alcohol, which I rarely use, and only works very temporarily, and then something else that I won't even mention... not drug-related, though.
Ironically, I have had a very "good" and "lucky" life, in so many ways... but that doesn't help, in my case. One should not merely think about oneself, and those close to oneself... that is one of my main "problems". Recently, however, you can add to that my main interests are being taken away from me... although that's not really related to my memory. However, I suppose that if I had my true love, I'd finally be able to be happy, anyway, as her presence would far outweigh all the negativity of this world.
I wish I had good advice to you, on how to deal with it, but I'm afraid I don't have that.
