Mother turned Bridezilla

Stop telling your mom anything about the wedding. If she asks, change the subject. Tell your venue not to take calls or make changes unless it is you that authorizes them. Time to cut mom out of the planning. The day of, have everything set up before your mom arrives, once she gets there make sure she is kept busy with pictures and things like that. And once again make sure your venue knows the situation and knows that she is not allowed to make changes on that day.

Is she paying for anything besides the flowers??

If so- you have firm discussion with her to cut the shit. Second, you don't let her pay for anything else, and maybe consider paying her back for the flowers so she doesn't even have control of that. and 3-speak with ALL of you vendors, DOC, everyone. Make sure everyone knows to stick to the plans you have and that they understand YOU are their client, not your mother. Also it may help to have a bridesmaid or friend on "mom duty"....my mom can be a bit high strung and causes me a lot of stress. my SIL and best friends both know my mom very well and were able to help diffuse any situations that may have caused stress by either separating the two of us or distracting her with other tasks that "needed" to be done. It was my saving grace and allowed me to have great memories with my mom without stressing.

Oh my word!!! I'd sit her town and tell her flat out cut the shit, be extremely firm In it. I also agree to contact vendors and let them know that No one but you is authorized to make any changes. Telling your FH family what to do?? No, that's a big hell no. It seems like she's viewing it as a society thing, could that be it?

My mom is very much like this, luckily she hasn't tried to take charge...yet. My dad would not deal with this shit, he'd tell her flat out to back off and shut up. My sister is on "mom duty" day of like @APZ suggests.

My dad and my sisters have all tried to talk to her about it and she gets defensive. She keeps saying she feels like I'm settling even though I tell her that it is really what I want. As the wedding has gotten closer, she's gotten more ridiculous. I'll definitely update my vendors about that so she can't make changes.

I'm terrified this will be my mom. She keeps trying to convince me to do a backyard BBQ... I just can't.. omg no. I want one day to be a princess, I want one day to celebrate my love with my family and friends. There's a venue in Ga, (I'm in south Florida) that I really want to road trip to see, from pics it looks exactly how I envision my wedding, she's telling me no, that I don't need it there. The hell, you've had two weddings, I want one!! My mom gets defensive too. I'm sorry your mom is stressing you out.

Depending on how crazy she is getting you may want to set up a password with your vendors - they are probably used to this level of nuttiness. A password will mean no one can call and make changes without knowing it. Also, second having one of your "stronger" personality friends or hiring a DOC to shepherd your mom's crazy.
