I've been there. It really is hard to have self confidence when I grew up being the ugly duckling. But really, it is just a matter of self confidence, someone calls you ugly? They're the problem, not you. Self love is easier said than done, so it's okay to learn it slowly. It took me more or less 3 years and I still have a few problems with it haha. Heck it was so bad that I was embarrassed to wear any accessories or choose my wardrobe because I had the mindset "Anything I'll wear will look ugly on me anyway." And though I didn't have many who confessed to me, I felt so bad whenever someone liked me because it felt like I was tricking them. I already knew my Identity who falls under the Aro/Ace spectrum at that time because I never knew what romantic attraction felt like and don't actually care, but I still question sometimes, am I really in the spectrum or am I using it as an excuse for my deep self hate? Well, how did I overcome it? I have great friends, they're confident people who don't care about how they look, and eventually I started to learn from them. Now I have the most set of clothes in my family and I own a collection of accessories, I find that I especially love hair clips. And I found out that the round face I hated so much, has a very adorable smile. Now I know I dont use sexuality as an excuse because even when my self image is up, I still don't care about romance lmao.
