Thanks very much for your comments. I'm feeling a bit better about things now. Just over a week to go :)
If you are feeling very anxious about the anxiety you may have later, it is better that you be put on some anti anxiety med, inform your ENT or anaesthesilogist.
But breathing thro the mouth is no big problem. Most septoplasty patients go through the same. Some ENTs use 'septal clips" post-operatively; and some use special nasal packs with a 'breathing tube' through it, don't know if it is available in your hospital or if your ENT is fond of it.
Any way it is no big deal. Try to smile at the new experience you are going to have !

Actually, I've had this surgery (amongst another 5 sinus surgeries, with several of them including packing) and it is NOT bad at all. You can breathe right through the packing.
The packing isn't placed in a location in which it would block your airways. You will have swelling, but it won't feel much different than having sinus congestion. Once everything goes back to normal, you won't believe the difference you'll have in breathing...it's a night and day difference!
Best of luck!
