I feel ya
I am totally the same way!
I am proud of who I am as a person, and I feel like if someone knew who I was, they'd be interested, but I don't have the confidence to just talk to people. With guys it isn't so bad, but with girls I just shy away. At one point in my life I was extremely depressed because of social anxiety.
Sometimes I tell myself that it's because I'm an introvert in general, but I'm not sure if this is true. I do feel like I am, but I'm not sure if this is a valid excuse. I feel like I don't have anything to contribute to a conversation. I'm in college by the way, so it would be nice to get this out of the way.
Also, I can't stand when I try and tell someone about it and they act like it's just bizarre. Like it's ridiculous to feel this way. I don't know if it makes them feel better or what, but it's silly.
Perhaps simply practicing would help.
