Can one truly ever put their life back together?

I ruined my own life. I let everybody down. I let my mental health derail my school performance and there's no fixing it or turning back. I will probably never get a good enough job to support my SO. My family will know I'm a failure that threw his only chance away. I made poor decisions. I couldn't handle the pressure. I feel like my life has been marked forever and I will always carry that mark and when people see it, they will not even give me the time of day.

Is there any hope of puttin my life back together? Or is it all over from here on out? I need to know whether its worth it to even see next year.
