Yes I can get quite scatter brained and forgetful either if I'm not on the right meds that make me feel spaced out or if I'm depressed. Then I can barely function and do things that I am able to do when I'm well. I can also get a bit of dissassocion where I feel like I'm out of my body watching like it's in a movie. That's when I'm most likely to be forgetful and especially prone to losing track of time and being unaware of what day or date it even is.
