If you let the experience of people ignoring you make you believe that you cannot be liked, you create that reality for yourself. You will soon that you see that reality everywhere you go because you believe it to be true. In the market, in the hall, in the studio, everywhere you go. It's not about what happened, it's about what you do after it has happened. Knowing that you can't control what others do to you, you can't bound yourself to the fear of what others will do or think. It's their task not yours.

I know it is difficult. Of course it's difficult to have a mindset shift but there's freedom in it. By treating everyone with respect, regardless of how they perceive you. Treating yourself too with respect and stop belittling yourself. If someone doesn't like you, that's fine. There are other people who'd appreciate you. Everybody has who they like and who hey don't like.

I'm not an expert when it comes to suggestions but I'd just say to stay respectful and continue your self-improvement.

Meet other people. There would be someone whom you could form non transactional and honest relationships with.

That's what I think. I don't know.
