Perhaps it isn't working today. Sometimes, these things take time. Sometimes, you're not in the right arena. Sometimes, you over analyze and speculate so much that it can drive you crazy. I went through months of anguish convinced my being single and not-wanted was a flaw. But, I had to realize that my single status doesn't mean I am not living. I started taking myself out. I would go on hikes, I would go to museums, and I had some penpals in the meantime just to satisfy conversation with another human being. I started feeling better about myself and eventually stopped caring about what other people thought or felt. My standards grew, I was able to say "No" to people I wans't interested in (whereas before I would talk to just about anyone in fear I might not EVER find ANYONE) and after several months of that, I found a handful of great prospects for a relationship.

I can understand how some people need companionship. I am one of them. I just really like having that person in my life that I can rely on, talk to, etc. But, you have to also be able to embrace yourself and realize "Hey, I can do the things I want still, even by myself".

Stop placing so much pressure to meet OTHER people's standards and focus on what makes YOU happy. For example, what are some hobbies you like? DO them!

If someone rejects you because you're being YOU, that is their problem, not yours. It seems like you're so eager to change yourself or present yourself in a way that is suitable for a partner. That is not only being fake, but it is also not satisfying for you I'm sure.
