Sorry for your stress but it will be sew worth it in the end. As others have said, take it one step at a time & time it will take, for sure. Don't rush into decisions & change what you didn't like in your other rooms & improve on the ones that you did like. Sounds easy doesn't it but we all know, change is sometimes tough. You are going to have a fabulous room when all is said & done. Good luck. Make sure you post the end results.
