I wrote to the person who my mother hurt so much

Okay, today I wrote to an old family friend, the woman whose husband my mother used to hurt her, the woman whose birthday she ruined, the woman who suffered from my mother's gossips and cussing, the woman whose husband cheated on her because of my mother.

I wrote to her to apologize and asked to help me bring back my memories.

If she's still married and tells her husband, he could tell my mother and she would get furious. All hypothetical, of course, but I still have this fear creeping up my chest.

I'm far from her, independent, but this fear, I don't know... it can be all-consuming, paralyzing, debilitating.

I'm proud of myself, but annoyed by fear. How can I get rid of it?
