Nervous or Coward?

I hadn't been nervous since I was born. I also thought myself who's with courage, and whatever I met in my life even it was hard or beyond my power, I would underestimate it at all and got anything funny to laugh. But today, I've met the feeling of nervous at first time.

I'd decided to make a phone call to her since noon, however, every time I tried to do so, I was timid. There were always a large amount of questions tangled me, what should I do or how should I do, even when I played the games or watching the movies. I hadn't been such confused before. The first time, played games with a such emotion, they seemed there was no attraction any more for me, and my mind was twisted. Until I did have made a phone call just now, I was also lost. I've no idea what to talk about and how to. With the passive reply, I've been lost more. Always says that care too much, mess too much. I've gotten it now.

I'm an atheist, but now I actually need the guide of something almighty.
