My step daughter is moving in with us, 24. Not only is she ADHD, she also is very opinionated and bull headed. It’s going to be challenging for me.

I had to smile, as I have been there, Rachel. Create “separate spheres,” so your computer desks etc. are not in the same room. Otherwise, you will go nuts receiving commentary on everything you do or say. It is important that you have spaces to retreat to. If you have a dog, announcing that you have to take the dog for a walk can put an end to some unpleasant conversations.
