Sorry to hear that you are getting so much grief about all of this!
We also just got over a very frustrating week in the wedding planning world too. I'm sorry to say that unfortunately when it comes to weddings, there are always people who think that they HAVE to say something about every decision you make....wether they are actively trying to make you mad or just think they are helping, they end up making you stressed out and irritated

.
I've gotten some good advice this past week, that I pretty much knew already, but didn't really listen til a good friend told me again. So maybe it will help you....
Your wedding is for you and DF. Yes it would be nice to try and make decisions that will make everyone happy, but there will always be SOMEONE who is unhappy. Ultimately it is going to be you and DF who will be looking at your wedding pictures everyday on your walls years from now...not your guests. If you decide to change something about your hair/dress/boquet/table decorations/whatever to please someone else and it's not what YOU want....you don't want to be looking at those pictures years from now and think "I hated those flowers (table decor, etc), I wish I got the other ones".
I think that she had a very valid point. Since she pointed that out, I have made a concerted effort to keep it in mind when people start complaining about stuff. When people have given unsolicited complaints I've started simply replying "Thank you. I appreciate your concern." Then just not let whatever it was they were complaining about bother me. They feel validated that they said whatever it is and that I said I heard them.
When people have said that some element of someone else's wedding is something that I should use/have, I've started just politely but firmly replying "Yes, Susie Q did have those (flowers) because that was what SHE wanted for HER special day".
HTH and that it gets better!
