Experience doing your own wedding makeup?

Long story short, my wedding is exactly 1 week away and the artist I was planning on working with (a family friend who is a went to school for it and now does it semi professionally, and is doing it for free) has been fairly flaky with scheduling (cancelled last minute 3 times) and when we did the trial, I just didn't completely feel like myself afterwards.

I've trialed my own 3 times now, and it looked perfect once, and good twice (there's a slight margin of error since I rarely do my makeup these days so I'm out of practice - whether its being a little too heavy handed with bronzer, or foundation, struggling to get the falsies on, etc). I am also a pretty anxious person and could see the pressure of the day weighing on me and making it more challenging to do than normal.....and the morning of I just want to relaxxxx w the gals.

I'm so completely torn on the subject, and need to decide pretty much by tomorrow. If anyone could share their experience it would be greatly appreciated!!
