Being in this mood is actually what causes this, people can feel the vibe on you no joke. You've lowk just gotta stop seeking the relationship actively and it'll come naturally. In the mean time try to find happiness in hobbies or other small things, it can really help to have just any group of friends/people you're close with just to hang out with, and if you're struggling, reach out, people want to hear from you.

Women can smell the desperation on you. If dating is your goal the only thing I can really recommend is just trying to be friends/friendly with more women in general. Once you stop looking, you'll find the right person naturally. P.S it can be a really big help to join clubs and things where you will be around a wide variety of people, you're not gonna meet your girlfriend in a girl walking down the street.
