Going crazy

So where do I start...Nick and Chris have been driving me crazy lately. They are always fighting and they don't listen at all. I am fighting a losing battle with them. I just wish I had a magic wand to make me a perfect parent and to be able to get my children to listen. I just don't know what to do. Me and Mark are at a loss for words. I feel like they have no respect for us at all. I know this is my fault we should of done something different. Actually we should of done a lot of things differently. Another thing that drives me crazy is every time we go to a store they always expect something again I know this is my fault. Me and Mark have a lot of changes to make and we are starting them NOW. They are still pretty young so I know with some work we can change it all around. I was not raised the best and I always want my kids to have everything and I didn't want to discipline them I wanted to be the fun mom. That has gotten me no where my kids are acting like spoiled brats now. I feel bad that I have lead them down this path but I am changing it. They will not like it at first but what kid likes to be told what to do. I will always give my kids unconditional love and guidance but they have to know that are rules and they can't have everything they want. Wish me luck!
