the past to change everything again

I just do not know with everything. feelings of longing there. but I do not want it all became boomers destroyer of happiness that already in get now. want to try running it's back to the past. but it was not possible. I got the present that can not go out so just as easily back your hand. and it's not the best way! sense that there is, but only a beam of the past are remembered back and destroyed again all make saturated confused and want to cry. perhaps excessively tacky but this is what I think. past that i do not know or not beautiful. but difficult to make in making me forget and continue to follow in the past. but I'm not past it destroyed everything that I've achieved. so? I will try to make try to forget the past and stand up straight staring at the sun that is in front of me
