Don't ever dumb yourself down just to be accepted by people. It seems like you have simply outgrown your friends. You are growing and becoming a different person. That is a good thing.

I've always been the type of person who most enjoys having "deep" discussions with one other person. You need to connect with people on a much deeper level than you are currently doing. Don't worry, there are plenty of people like that around. You need to go out and find them.

So... Get out of your comfort zone and start trying new things. For instance, try swing dancing, start taking lessons. You'll find an entirely different caliber of people at swing dances than you will in bars.

I think you are doing fine and the fact that you are concerned about this and reaching out to others to find a solution tells me that you will most likely find what you are looking for.

Good luck in your search and keep on learning and growing like you are doing. It sounds like you are on a great path.
