Dilemma

I have seriously been contemplating asking R out or at least make it super obvious that I'm into him.

I'm so fucking scared though. Is this what boys go through when they think about asking a girl out? I'm just so tired of waiting around. I'm tired of wondering "what if." What would happen if I did ask him?

a) He says yes. We get to know each other. I already know he is amazing so I know I would enjoy spending time with him. There is potential for a relationship or at least getting to know each other better even if it doesn't work out.

b) He says no. It's incredibly awkward (mostly because I make it awkward). We avoid talking to each other for the rest of the time I work at Officeworks. I lose a really cool friend. Everyone else at work finds out and there is constant tension and awkwardness in the air from then on. I start dreading going to work and checking the timetable in the hopes he's not rostered at the same time as me. 

There's so much to potentially lose but so much to potentially gain as well. 

Can someone advise me? Someone who has been in a similar position or who has made the first move. How do you get over that feeling in your body that is screaming at you to not do it? Or how do you manage to listen to the part in you that's screaming at you to do it and just see what happens?

I'm so confused.
