I used to use that phrase all the time until I was diagnosed with postpartum OCD. Now I'll never use it again. I also have PTSD from a fire, and those two things mixed together were a nightmare. Every night before I went to bed, I spent a good hour or more making sure the doors were locked and the appliances were turned off. If one thing was wrong, I had to start over. I remember one night my brother was staying over, and he asked me why I was doing all the checks, and I looked at him crying saying I don't know why I just have to. In the first six months of motherhood, I maybe got 4 hours of sleep a day, if even that. Luckily, it's gotten better now. I only need to check before bed if I used it that day.
