My father and mother have always been there for me. I've been REALLY sick and they were always there. I love them both very much, and I have told my mom I love her. However, I just can't say it to my dad, even though I wanna. It would just be too awkward and embarrasing. Besides, I know he knows it. Yet, I feel I should tell him, because I'll probably regret it if I don't. He's even told me he loved me once, and all I could say back was that it was good to hear. What an asshole I am. I wanna say it, but I just can't. Is this normal and how should I deal with it?
