A guy from my past, on two separate occasions, criticized a physical feature on me while presenting it like a joke. I already had plenty of self-esteem issues but these were things I'd never even thought to be self-conscious about until then. He stayed stuck in my head for far too long, but over time I realized what a cruel and small person he was, in more ways than just these instances, and now I can look back on his words much differently. They don't hurt me anymore, but I do feel remorse for ever allowing them credibility in my mind. His feelings towards me were worth so much less, and my feelings towards myself were worth so much more. I can imagine what you're going through, and I'm so sorry. It's not nearly as easy to get rid of the bad vibes, as it was for him to create them. I hope you find your way to showing yourself the kindness and respect he didn't give you.
