Don't get discouraged waliandayanna! Even though it may be disappointing about the number of guests backing out and not making it to your wedding, at the end of the day it's all about you and your hubby and the memories that you two will be making together!
I am dealing with the same thing and I want to lose my mind but honestly it's not worth trying to stress myself out. The way I see it is when I bring back the pictures and video to the people who weren't able to make it, they'll be disappointed what they missed out on!! hehe
Best wishes to you!
