Do I really have to let my life fall apart because I didn't think I'd make it this far?
Sounds deep. What did you do to let your life fall apart?
I drugged and partied too hard and didn't care about my girlfriends.
Everyone regrets some of their life decisions at some point. You shouldn't have done the things that you did, but you still have the ability to turn your life around and make things right.
Wtf I'm only 26, I still have plenty of time to live.
That's the right attitude! 26 is indeed young, so you've got plenty of time to adjust and do what it is you need to do to get your life in order. Like you said, you got plenty of time, so it's never too late to pick up the pieces and get your life back.
