I Feel Like I Have No Emotions

Good thought process. Most people tend to just stick to one and get stuck in it, rather than extrapolating.

Only thing you have to do is use a bit of caution. I really love this explanation of human relationships, someone recently told me about.

The hedgehog dilemma. A group of hedgehogs seek to move close to one another to share heat during cold weather. They must remain apart, however, as they cannot avoid hurting one another with their sharp spines. Though they all share the intention of a close reciprocal relationship, this may not occur, for reasons they cannot avoid. The hedgehog's dilemma suggests that despite goodwill, human intimacy cannot occur without substantial mutual harm, and what results is cautious behavior and weak relationships. With the hedgehog's dilemma, one is recommended to use moderation in affairs with others both because of self-interest, as well as out of consideration for others.

Of course, you could also take it a different way. Yes, focus on some degree of caution, but also get close enough to where you can form a satisfactory relationship.

Sounds like you've gotten yourself in a loop, like the guy who runs down the beach to jump in the ocean, then, when a wave comes in, he runs back up the beach to avoid it. There must be some programming in you that's keeping you in this holding pattern, keeping you from diving into your never-ending feelings. Take a look at your history, at some event or events in which you were afraid to feel, something that trained you to go the other way when you had strong romantic feelings. I think you'll find the answer there.

Crushes can be wonderful and awful, I was like you and they were just a constant rollercoaster. It'll get easier as you learn to identify and work with your emotions.
