Don't ever feel embarrassed, I dread to think how many DM's she has right now, she has empowered so many victims by waiving her right to anonymity and who relate to her story, it's natural that victims want to reach out to her
It was a worthwhile thing telling her your story, even if she hasn't got around to reading it yet, it's helped YOU, just by writing and sending it to her by taking the pressure off of your shoulders by having to carry it by yourself
Keep your head up high and be proud of yourself
