I personally think you're doing the right thing, assuming your assessment is honest and not just a tool for beating yourself up. I've had a few friends who basically felt the way you describe, but compulsively pursued romantic relationships anyway, seemingly under some bizarre illusion that "catching" someone to dump all of their pain and "no one understands me!"'s onto would make them happy. They invariably ended up wasting their time and that of their intended partner.

If you can figure out how to be happy and fulfilled by yourself, you'll probably have something to offer to a sufficiently compatible person. And it's not like that effort is wasted if you never end up finding such a person.
