Obviously, all people are different, but in my opinion, If you aren't a little scared of having feelings for someone then you're silly xD
Liking someone puts the person in a vulnerable position, and nobody wants to be vulnerable, that's why sometimes we get scared about having feelings, scared we will end up worse off because of them, or try to hide them because we find it easier than dealing with them.
But, You need to face them, it's very hard to do, everyone struggles with it, but in the end it is worth it because you will become a stronger person emotionally, Feeling something is so much better than being numb.
feelings are like a dark tunnel, you can't always see the light at the end of the tunnel, but if you keep moving through, you will find yourself in a better place. :)
