How do I stop being invisible to people?

Mostly, when I try to connect to people I initiate conversations. Yet, they don’t notice me. They don’t think of me when they are going to do something fun. They don’t ask about me. They don’t include me in their life/friendship circle. I haven’t made any friends since high school. That’s almost 10y ago..

Don’t get me wrong; people are friendly and they tolerate me. But that’s about as far as it gets. They are not interested in who I am, even though I ask about them all the time. I don’t know what I’m doing wrong. I’m introverted and I don’t know how to connect to people anymore. How do I stop being invisible to people?
