Too Nervous? - Sydney, AU

Hi guys.
I have been following this site for....this is probably the fifth year...lol. I will finally be doing my rhinoplasty in Two months time. But I am having some unexpected problems and I was hoping to get some support.
For it being planned two months ahead, I think I am a little too nervous. Not so much to do with how the nose is actually going to look like, but actually undergoing the procedure. Maybe it's the fact that it's open instead of closed rhinoplasty. The idea of getting cut open and what not. The doctor said my tip is too bulbous, that I have no tip, and so opened would be best. But it's probably to do with the anesthesia as well. I'm scheduled for general, and I am nervous of being sleeping, and until yesterday, I had no idea that they shoved a tube down your throat so that you could breathe. Of course, I was totally against the idea of being awake during the procedure. But now, the idea of using local anesthesia makes me feel a bit more calm. However, I just see it as being an incredibly uncomfortable situation, considering especially that it is an open procedure. I will ring up my doctors office today and discuss this with the receptionists. But has anyone done open rhinoplasty with local anesthesia before? If so, care to share the experience. Another thing that makes me feel guilty is the amount of money I will pay. I feel like cowering out altogether, and just staying in bed, like I do when I have uni exams, lol. But I want this. My nose bothers me, it's hard to breathe, I feel pain on it every now and again. I want this to be done. I want a normal, natural clean looking nose and a proper functioning nose like a normal person. I'm a male adult, and teenage girls writing on this sight are braver than me. I feel so sick about it all the time. I'm not even sleeping right. My modified post-operation picture looks good too. I use this as motivation sometimes. I feel better writing about this. I want a friend to come with me when I do the operation. I think a member of the family would care too much. My friend will joke around all time and lighten the mood. Do you think I'm too nervous about this? How much am I exaggerating? (I hope I am exaggerating).
