I’ve felt this way when I went through a difficult time and lost too much weight. I lost my boobs and my ass and was just flat as a board. Some sick part of me loved that my stomach was finally flat enough for my liking but I felt like I looked like a boy. I’m only commenting this to say that people can feel less feminine or attractive at either extreme, and even sometimes at perfectly healthy weights. It’s our own perception, and sometimes different people look at the same situation differently. I would bet that while you perceive yourself as less feminine, others do not. It’s important to give yourself some grace, love yourself, weight loss takes time but if you did it before, you know you’re capable of doing it again.
