The guy who I love hates himself :'(
I'd agree it's probably much harder for guys who don't have much confidence to form relationships, because stupid patriarchy dictates y'all have to make all the first moves.
It's a viscous lie that hating yourself makes you unlovable though. Hating yourself can make people kind of insular; you're so close up to yourself that everything gets distorted and all your flaws look huge, and you're likely comparing yourself to others, a lot of whom are in fact just as insecure but you can't see it. From someone else's perspective, you may be the most perfect person ever.
This guy, who I mentioned before? He's told me all these things he perceives to be wrong with himself, and it hurts how unhappy he is sometimes; because to me he is truly so beautiful.
I hope that you find someone who loves you so much that you forget how to hate yourself. You deserve to find that, and it is possible1

Girls are attracted to confident guys. It's almost impossible to trick a girl into thinking you have the swag. But you can fake cheerfulness. It works almost as good as confidence.
If you pretend to be cheerful enough of the time then it will become real cheerfulness.
As far as loving yourself all I can tell you is that you are the only person inside your body. It is up to you to take care of that guy inside. He will always be there for you, it would be nice if you could always be there for him.2
