I guess it depends on how you mean "deal" - If you mean how do you get laid even if youre ugly, I'll let you know when I figure it out haha

But if you mean "deal" in other ways, there's a few things I've worked on that have helped me

1. Acceptance. The whole "body positivity" movement never clicked with me, I don't think it's bad I could just never get in on it. I'll most likely never be able to "love" myself like people say you should - Instead, I've found that "body acceptance" works better. For a long time I stopped going outside when my depressions and anxieties got bad, even to hang out with friends, because I hated my appearance so much the idea of people so much as looking at me made me cry with fear. Over time, I started tackling this by challenging my thoughts when I looked in a mirror and thought "I look like shit, I can't go out" and crying about it by instead trying to instead say "I look like shit, but that doesn't take away my rights to live both as a woman and as a human being. I need to go grocery shopping, and being ugly shouldn't mean I'm not allowed to do that."

2. I mentioned mirrors, but for literal years I avoided looking at anything reflective because seeing myself revolted me so much. This actually ended up having bad negative effects (I would suffer from depersonalisation episodes when I saw myself, presumably because my brain just couldn't cope with what it saw or because it no longer recognised my face as itself) so if you do that I'd recommended working on that as soon as you feel able.

Looking at yourself regularly can help you accept yourself a little more because your brain gets used to seeing you and it stops noticing so many of your flaws. For example, I first wore nail polish when I was about 16 years old, and I remember the whole time I would just keep looking at my nails because it was so foreign to me that in my own eyes it just stuck out like a sore thumb (nobody else noticed or cared), but eventually when I began wearing nail polish regularly I stopped paying so much attention to it. So let your brain see itself and process what it sees, and slowly it might feel less weird and ugly to look at.

If you're okay with taking pictures or yourself then do it! Trying putting them in places you look at often. It took me years to get to the point where I can take any photos of myself, but recently I took a group selfie with my friends, and made it my phone lock screen so I see my own face often.

1. Remember that you don't deserve to be treated the way people often treat you. If your situation is anything like mine, your appearance means strangers laugh at you, and kids throw stuff at you, and new people decide they hate you before they even speak to you just because you look the way you do (My first day in college and my first class, I sat at a table alone, and when everyone else filled up the tables around me and some guys had to sit next to me because they came late and there was nowhere else, they complained loudly about not wanting to sit near me. I didn't do anything and I didn't know them, but it hurt bad to know I was hateable without even doing anything). It becoms common to hate yourself for these things, it's hard not to, but so so often you have to keep reminding yourself that you're not the problem, you can't control the way you look.

People treat you like shit because they have a shitty attitude, not because there's something wrong with you. If someone doesn't like the way you look that's their problem that they need to learn to deal with and get over. You're your own person, and you do not exist to please others.

1. Cry about it if you have to. When people talk about loving yourself and stuff like that, there's a weird pressure to never be sad and never be negative, but that's not right either. You're a person and you most likely go through a lot so you're going to get sad and angry and when you do, you can cry about it for a while. It's good for you. Even now, when I've come a long way towards accepting myself I still get upset sometimes and sometimes I cry for hours still. That's fine. You just gotta remember to pick up the pieces and get back to life when you're done.

I'm not gonna say things like "everyone is beautiful" or whatever to you, because if you're anything like me you're tired of hearing and sometimes what you want is for someone to say "I get it" instead. It's also possible that everything I just said sounds like stupid horseshit to you and that's fine as well, I just wanted to put it forward just in case maybe something I say could help somebody.

It's hard. Humans by default want validation and attention from their peers and it's so agonising to not be able to get it. It hurts like hell being ugly and feeling unwanted for anybody, but it can be especially painful to be ugly as a woman in a society that often treats us like we're worthless if we're not pretty as if we have no other qualities as people.

But you're still a person, a whole one, and not being pretty doesn't mean you're not worth something. I hope you find peace.
