You can’t live in shame from your mistakes. Forgive yourself, learn from your mistake, and do better next time.
Those words, no matter how true that are, don’t make the shame go away, don’t make you forgive yourself, and don’t make you do better next time.
What really does help though, is connecting with others who can help you rebuild and learn from your past. Write about it, talk about it, and try to help others make better choices.
Here’s a poem

Retractions
Here I sit with not one fake mother fucker in my face.
I’ll humbly admit that there are some days I shift.
I’ll suggest something I don’t agree with
and when I become conscious of my falseness,
I retract it as quickly as I can.
It’s just much easier
to be elsewhere in my mind
and follow suit with my mouth.
Being aware of me at all times
is quite a bit of work.
I assume it is for most day dreamers.
