Legos blocks come in all sizes. Some pieces have one or two posts; they can only connect to one or two other blocks. Some Legos have enough posts to connect with dozens of other blocks.
People are like Legos. We're all made differently. Some of us can connect deeply with only one or two others in friendship; some can have close friendships with many people. Find out what type of Lego you are. And don't feel like you have to change it.
