Sometimes you don't know

Sometimes you don't know what to do in life...
and I feel so stuck right now I feel like a horrible person like I've fucked up so much stuff in my own life and in others'.
No one is perfect, but I can't help but beat myself up over some things that have recently happened in my life.
I just want to be happy. It feels like that is too much to ask for in this day and age.
