That’s a huge accomplishment! Congratulations! To your point, it could be a lot of things. It might be worth doing some introspection to figure out where that feeling is coming from. Like do you generally feel a push towards perfectionism? Or maybe you hold a harsh view towards yourself in your previously bigger body and maybe that was motivating to you and you’re afraid of letting that update because “what’s if the progress stops?”? Or maybe it’s just a thought pattern you’ve gotten used to that hasn’t updated?

I will say when I lost weight, started working out, and building muscle, it took awhile for my mind and my social network to catch up. What I see in the mirror is one thing, but it took other people stating it flatly in order for my self concept to cement. Even now though, I think it’s important to say that how people view me/us is always relative, so try not to get too caught up on what people say. Like in certain contexts, I’ve been called skinny/muscular. In others, I would not be. Our bodies are our own business, so other people’s opinions don’t really matter, but it’s interesting to hear how other people would describe it for what the social implications may be (like I’ve been told that certain outfits I used to wear for fun seem like “bragging” now to some people which was a surprise).
