Past vs Present vs Future

Past: The past...eh I hate the past...why cling desperately to events that have already happened...people that were once important...if they are not important anymore...then why even bother continuing a relationship with them...it's pointless...I don't understand it...little suzy still hung up over her ex after he's moved on and got a new girl...why care...it just causes complications and confusion among the involved people. It causes jealousy, anger...and even in some cases betrayal...so why even bother with the past...*O yes I wanted to kick your ass at one point and time...but we're cool now...let's be friends* Fuck that! I'm not gonna be your damn friend...you turned on me once when I thought we were friends...what would stop you from doing it again. *O you were such a good boyfriend, we can still be friends* fuck that...you're an ex for a reason...and I don't want anything to do with you...why should I have you in my face while thoughts of things that happened between us flicker through my mind...it's ridiculous...It's just like the people that sit at home and bitch about how they wish they were kids again...no matter how hard you wish...you're still going to grow old, you can't rewind time...so stop bitching about it...seriously...grrr...makes me mad, so stupid..that's why I'm away from my past...so no having to stare at stupid ex's trying to carry on awkward friendships...no having to deal with people that hated me for the longest and wanted to fight and shoot me and shit, now wanting to come and smile in my face and wanting to be friends...such bullshit...Why hang onto the past when it just causes frustrations and anger and confusion...someone please answer that for me

Present: The present...live life to the fullest...treat every breath as if it were your last and all of that happy stuff...hmm, just living day by day...That's enough without having to worry about stupid people from the past and bullshit that happened with them...Just live in the present, plan for the future...forget the past and the bullshit that's in it...meeting new people, starting new friendships, it makes so much more sense than trying to salvage and fix fucked up shit from the past...why not just start anew?? Sure the present will soon become the past...but you know what...if bullshit happens...or a friendship becomes ruined because someone decided to start acting stupid then forget them...tomorrow is a new day and another opportunity to meet someone new and replace that friend.

Future: The future is what we are all supposed to be planning for. What everyone is supposed to be prepared for...well you can plan your general path for the future...like education wise...interactions you'll have with friends, things along that nature...but no one knows exactly what is going to happen in the future...it's like the big void that you have no idea what's going on in it but one day you get sucked in...and when you do, it doesn't turn out to be that bad. Hmmmmm...so why would one be stuck on the past when they have the future to look forward to? Maybe I'm just missing it...but I truly don't understand it...One can have hopes for the future...that's fine, it's good to have dreams of what you want to do.

Just thinking alot about all of this...so if someone has answers please share.
