Personally speaking, it does come down to how you feel. I’m up to a weight I used to stand in the mirror and pinch and poke myself about before, but with some muscle and a little more self confidence, I do look a lot different. I don’t have my previous anterior pelvic tilt that made me hold my weight awkwardly and I lift heavy around 4x a week. Muscle mass has made me more confident, and it has me feeling better, wearing my clothes more confidently because even though I weigh a weight I used to hate, I still take care of myself (even if I could be doing more). People are still almost as nice to me as I was a much fitter, 20 lbs ago. It is, as others have said, a degree of self acceptance. I’ve struggled with my weight for almost a decade but only recently do I feel that it’s just a natural pendulum swing and I am still the same person, “skinny” or not. I still can run, I still lift heavy for a lady, and I still look rockin’ in a bikini. You just have to learn how to feel this way.
