Please tell me what to do

Ok so I’ve heard it all, “you don’t need anyone to be happy,” “the right person will come when you least expect it,” “focus on yourself,” the whole spiel. But I am lonely on a fundamental level. Like, physical pain and legitimately detrimental to my mental health. And it’s not so much that I don’t have a boyfriend that bothers me because I consciously know that I’m not in a place where I’m ready for a long-term committed relationship. What bothers me is that no one is interested in me. No one ever looks twice. I’m just not worth a second glance. And it’s really painful. Can someone please tell me what to do? I just feel so alone and there’s only so much whining I can do to my friends before they get pissed.
