If you want to improve your emotional outlook now, may I suggest that you stop wasting energy on a problem that belongs far more to the past than the present. The last thing you want to do is drag this with you into the future. Or is it? Do you perhaps feel that if you keep going over the old ground, you will unearth something valuable? You need to be pretty sure that this is likely before you let yourself get caught up in a complex web of argument and counter-argument. You have got so much more to do with your precious time.
