Why do I get the impression that you base your entire sense of self worth, minute by agonizing minute, on whether or not you "have a woman"? People and relationships are not *things* to be possessed, and no one with any self respect would be attracted to someone who comes off as even a quarter of how needy you're coming off as.
Here's a tip - pretend that you love yourself a great deal and that you're genuinely interested in learning more about the everyday wonders around you. Pick up a new hobby or three, go to a book club, take ballroom dancing lessons. Don't just sit there, do something.
If someone picks up on your new positive vibes, talk to them without worrying about whether or not you'll end up with them for the rest of your life. Pass off your interactions as nothing Earth-shattering at first. Be cool. Don't fawn over them. Don't burn out in an anxiety spiral. Don't hang the entire meaning of your life on how fast you can become a couple.
The beauty of all of this is that it makes the time that you spend by yourself more pleasant, even if you're not currently in love with and/or having sex with someone else. Believe it or not, it's possible to be single and happy with yourself, and if you're happy with yourself then you're more likely to draw others to you.
Now stop worrying and go out and be awesome.
