The best advice I received when I went through that, was to stick with the truth, and just the facts. Ignore the extra stuff because it's all noise.
Pare down the nonsense....sort through what really matters to a judge.
They know the emotional stuff will rattle you and that exactly what they're hoping for....distract you so you make an emotional decision.
Also, remember that you have the truth on your side. You have the easy part. The truth is always the truth. It's the liar that has to recall which lie he said, and when.
Don't waste an once of worry on the letter D13 left in the house. In the bigger picture, it will not be a deciding factor. Courts know everyone has moments when they could have been better. The more you own up to your honest actions, whether favorable or not, the more credible you will be.
You are so smart to come here and receive such incredible insight to your sitch. I know it's so hard, and so scary. Especially when the stakes are this high....the kids. It doesn't get any higher than that.
