You believe you lack pre-requisites women require. Truth is, there are loads of short guys, ugly guys or otherwise challenged guys that get what they want out of dating, whether it's lots of random sleeping around, or a committed relationship, and everything in between.
Please don't talk about giving up on relationships. Online dating might actually not be the best choice for you. It creates the illusion of control and comfort from your living room. As you saw, it's tough work and you don't really learn much from it, not as much as you could learn if you spent the same amount of time outside meeting women.
Try to meet women in your day-to-day activities. Join classes. Get active. Go to bars and parties. I don't know where you're coming from, but if you're shy and lack confidence, make a point to talk to other people, and that includes attractive women. Also, you need to have a mindset of abundance, not of scarcity. There are plenty of women that'd like to be with you, if you go out to meet them and show them your true self and get your act together.
You'll get vastly better over time. But it does take time, so don't give up after 1 week :-)
