Aw, give yourself a break, you're an introvert who has found someone to connect with deeply. It's good you are aware of being clingy, that's the first step to being not too clingy. I say, set boundaries, and don't feel bad when you aren't able to convey your whole personality in one go. Don't share too much of yourself, give time for the person to know you. If they lose interest quickly, then they are not worth your time. Quality friends are more important. But it is unavoidable at times, especially if you come across someone who gets you, I guess your heart will be able to let you know, then you can pour out your heart and soul without fear of being clingy.
