Everyone has felt this impulse toward another person and sometimes it can be overwhelming. You can't help how you feel but you can learn ways to overcome the way those feelings make you feel.

You can't just stop liking someone but maybe you can look at it from a different perspective. Seriously consider the reasons you like him, why you feel like you will "explode" and whether or not you are allowing yourself to be set up for continual disappointment which is not healthy.

It's not good to dwell but it is often helpful to think things through and continually remind yourself of what is healthy for YOU. It's like when you choose to eat a salad instead of a hamburger, you immediately know you want to eat a delicious hamburger but something inside you compels you to choose the salad because you know it's better in the long run. Whether it's because you have high cholesterol or are on a diet you make a decision to not choose what you want but instead what you need.

If this isn't something that is good for you your mind and body will help you overcome it.
