Is it normal that im either not pretty at all or just not lucky?

I'm "ugly", too. I have torticollis, so my head is slightly tilted and my left cheek looks a bit larger than the other. I've gone to therapy and chiropractic (therapist did not recommend later), and it recovered a bit but is still there. Well, I somehow DID get lucky (...I don't like the song "Get Lucky"... Sorry...)! I have loved my friend for a while and didn't know if they did back. But, however, they did show it in some sort of way...:

In school, we had to choose partners, who were the opposite gender. I had a friend, who has been my bestie in 1st grade). The two were very good friends and yeah. So, a classmate asked my guy friend, "Who are you gonna choose?"
My friend said, "For what?"
"Partners."
"Oh! Um... I have a list... In first is (name of my first grade friend) because she's super funny, but she's a bit rude... If not, then my other choice is (name of Pika-girl) 'cause she won't be rude about correcting my mistakes."
"Ooh!"
I was across the class when he said that. And when he said who he's choosing, I heard my name, too, so I turned quickly towards them. The classmate saw that I was listening, so he raised his eyebrow and snickered. I just did my normal confused face... It's also my innocent face!
They ended up choosing me instead, and our "relationship" grew a bit more everyday.

But, yes, I am not attractive, too, and some guys would just go for "hotness".... And the REAL MEN go for personality! They would never be afraid to be with you. It's only if they care about you that matters. Alright? So, don't worry! Anyways, we're pretty much similar and if I can do it, you can do it too! Just make some guy friends! DON'T change your personality at all, though! Be yourself and show them your beauty! Okay! Hope this helps!

You'd be surprised who people are attracted to. You don't need to look flawless for someone to love you. Every day you can see thousands of people who you might consider unattractive who are in loving relationships. There are 3 billion guys in the world, and all you need is one of them to be attracted to you.

I'm not going to sugar coat it just to make you feel good. You came here for advice for your problem in reality, and this whole "beauty in the eye of the beholder" thing is true, however not as much as people like to push out there, probably not even half as true, as most people identify beauty the same as others. Yes, they may have differences, different hair, eyes, nose, and so on, but pretty is pretty, that eye of the beholder thing only goes that far and wouldn't apply to those that differentiate from what can be classed as a beauty. I am not saying you are not attractive, you may not be, this jaw thing may not be bad as you claim, your other qualities may outshine it, or it may make you look terrible. A picture would of done the commenters a favor to know how bad it is and if it would have any real bad concequences to you in this aspect of life.

Anyway, on to the advice part.
There are guys that will look past it if given reason to. You say looks pave to personality, so you have to bring your personality out first and give them reason to put attention on that than to just look at another pretty face around you. Be confident, fun, and so on. If you aren't physically appealing, then yes, people are going to overlook you for prettier people if they have no reason to look at you first, so if you want to find someone you will have to do the initiating instead of expecting a guy to come to you, you will have to put a bit of work in, make them connect with you on a personal level to the point that your personality carries your appearance. Again, if your face is as bad as you make it out to be, you have to be the one introducing yourself, introducing your persona, because people won't look at you and come to you based on your appearance, and unless they are staring at you all the time, which is unlikely if you are unnappealing to the eye, then you have to bring your personality to them.

Another thing would to stick to the level of appearance you are on. Do not expect to pull a gorgeous guy if you are not on the same level, there are pretty girls out there with good personalities too, ones that would appeal to him more than your personality, he has more opportunity with the people he can be with, so aim for someone your level, given someone in your circumstance you should have a bit of empathy to how someone your level may feel, and you can't exactly feel it is unfair you can't find love by excluding guys on your same level while doing to them what you find people doing to you as unfair; overlooking you due to your appearance.

Hopefully my advice serves well, as I am sure all you'll get is the equivilent of "chin up, gurl"'s rather than things that may actually help.

You really need to accept yourself as you are. I'm not saying you shouldn't have the surgery, but honestly, are you so shallow that a deformity such as yours would turn you off a really great guy?
Looks fade but the person inside is the person you should love, including yourself.

So, you're basically a female version of Jay Leno.

Although there is someone out there for you that does not care about your jaw, your option of surgery is a good choice of improving your self esteem and attitude. Go for the surgery and move on with your life, advice from someone that knows how you feel.
