I'm in my thirties and I'm not married. I feel ashamed.

It's a little late to be 30 and not married. Pay attention to parents at home. I was worried about you, too. They are eager for their children to get married and start a family as soon as possible. This matter should be understood. But it's too late to get married He humiliated you and your family. You should still explain to your family why you are not married, so that they can understand you.
