being afraid of love?¿?

Tia
I'm in love. It's a feeling of complete and utter joy and excitement but at the same time there's a feeling of fright as if I'm scared of this love that I'm feeling. I don't know if this is normal or if people have a similar feeling but I feel as if I'm so in love that it's scary... what is this feeling? I feel like I'm sounding like the grinch or something lol but does anyone else feel this???
