Anyone else feel undesirable but want romance?

I have to be frank and honest: I am young, I want to get into a relationships. Explore. Everyone around me is in a talking stage, in a relationship, just able to be seen in that way. Desired. As if the list couldn't grow, I have yet another reason to hate my social anxiety: I can't flirt. Can't get into a relationship. And to worsen the rubble, I'm insecure about my body. Can't look or feel attractive. I really feel like half a person in these moments, like I'm incapable of doing. It's just not in my toolkit to be desirable, being anxious and quiet. Like, through and through, I seem to hate myself. My body. I bought the best accessories. Felt terrible because I felt I looked terrible.
