Spock - You are adorable, and you have a cute personality and sense of humor to boot. A lot of the things you think about yourself are turned upside down.
A - SIngle mom, spends weekends racking up notches on her bedpost, lots of sexual partners, has acquired lots of bedroom tricks while picking up a nice case of The Clap. Puts extra cash towards boobs.
B - Single mom, responsible, too busy working and taking care of her kid to be in the bar scene, not a lot of sexual partners, a bit shy, insecure because she doesn’t have a lot of experience in bed, might need a nice guy to be patient and help her to get her game on.
I’m guessing most of the men here would choose B. In fact, they’d be happy to help you get your game on, and would see it as a positive. 
Sincerely, some of the things you think are a negative are a positive here if you would just own it.
I have a friend who just had her breasts done because her AA boobs were kind of a monkey on her back in terms of lack of confidence. She’s about our height, with a bigger booty, so now she looks more proportionate and she’s very pretty. On the other hand, I’m comfortable with my smaller boobs. Some of those large breasts only look pretty in a bra, otherwise they are sagging and orbiting your waist. Mine are proportionate to my hips, but most importantly I feel like they are a positive. Hey, it’s the ideal for ballet. Many men prefer smaller natural boobs, especially on a small woman. It’s all about proportion, and creating the illusion of an hour-glass. And it’s about owning it with some confidence. Maybe cultivate some female friendships with women who can give you some support and perspective.
I think you and I have very similar builds. Petite, small-breasted, bigger through the booty and thigh. There is a whole art to dressing a petite figure. Some clothes just flat out don’t work for us. If it’s boxy or oversized it’s a NO. Any crewneck t-shirt like the guys wear is going to look frumpy, flatten your chest, as well as add 20 pounds because it doesn’t show off your small waist. Long tunic tops and empire waists make us look short and square.
There are petite bloggers who talk about this stuff and can help you out. The same with learning how to do some really natural make-up that you’d be comfortable with. You may as well go with the statistics. Most men prefer natural make-up and clothes that emphasize an hour-glass figure. It’s all about proportions. Hey, that’s what BBing is anyway - creating an illusion.
These may not be your style, but you get the idea. Yes, she’s a tiny Asian, but the same rules apply. You don’t have to spend a lot of money to have a wardrobe that flatters your figure.

The hard part is putting forth the work to overcome your anxiety/OCD/confidence issues. It won’t go away by just hoping. I’ll bet you’re in the same place you were in with this a couple of years ago, right? So, read some books about Cognitive Behavioral Therapy for Anxiety, find a support group, talk to people who have overcome these issues and get on it. Seriously, most of this is coming from the same place. Anxiety - Lack of Confidence.
