Miss what?

Miss her miss him miss them miss those miss what? Well, I don't know what I miss but I just miss everything and I hope I can go to the past, lived my life to the fullest and remember all the things that happened in my past and apologies to everyone and when everything is okay, I can go back to the present me and well, maybe I would miss my past again and go again to the good memories in my past and memorise everything and go to the present times infinite. Can I?
