This quote is from the movie Wall Street - but I have always remembered it when I feel ashamed of my mistakes and it's hard to see an end in sight.
"Man looks in the abyss, there's nothing staring back at him. At that moment, man finds his character. And that is what keeps him out of the abyss."
Sending good vibes your way. Keep your chin up, own up to your mistakes and try your best to never be in this place again.
