Can’t forgive myself for my past, it’s eating me up

I’m struggling with a lot of shame from my past. I never had sex outside of marriage, but when I was a teenager I talked to a lot of men and some of my messages weren’t modest. Now that I got out of my forced marriage, those feelings weigh on me even more. I feel as if I’m tainted and unworthy of love, like my worth is decided by mistakes I made years ago. I have even started taking pills because I can’t move past this guilt.

I don’t know how to forgive myself or let go of this.
