Can guilt decimate you?

Can guilt take years rotten of your life?Can guilt decimate you?
I would have an idea that that if you suffered from severe guilt about something and it artificial your sleep and eating customs for a long period of time, after yes it could. I think it would be best to merely come clean and business with the consequences if it's that impossible. Good luck to you.
guilt could lead to clinical depression so yes to both
No...
I devise yes, to both. If guilt becomes so severe, it can motive depression and the person to newly feel so unpromising about what they did, that they decimate themself to get rid of the guilt. And if it doesn't return with to that point, they can still be so sickened that they don't feel resembling eating or doing any ordinary activities, thereby diminishing their point of life, and probably decreasing their time span as a result.
