Heartless ?

I don’t know why, but this days I feel like I can’t feel anything. I’m talking to this boy now and like I act like I like him. I’m always checking my phone to see if he answered, always wanted to talk with him and etc, however idk why but I just can’t feel what I used to feel when I used to fall in love. It kinda feels like I’m numb or something because it’s happening with everything. I just can’t feel any emotion towards something and when I try is like my chest is locked or something, I just can’t explain.
