I've recently came to a realization that I'm falling in love with my boyfriend and I have been wanting to tell him but everytime I get a chance I get scared and don't say anything. These past couple days I have felt like it has been eating me inside not telling him. I started crying the other day for no reason and I'm not one to just cry like that. I also have felt randomly sick to my stomach, almost like puking. Is this normal? I have never felt such crazy emotions like this.
