vent?

I've only now figured out that I always imagine how I could go back in time and how I could change some things to make my life better and somehow I always think that I could turn back time only so I can be all sad a few minutes because I realized that I actually can't turn back time and that I just imagined that I could and that I convinced myself that I could turn back time and this always happens over and over again and I don't know why
