I don’t know where else to ask, so i’ll ask it here.
my mom kind of has a history of mental illness (she’s never been fully clear to me but i’m pretty sure she’s had diagnosed depression). For a while now, she sometimes gets into these weird “moods”. she’ll act really weird. in the latest one she slowly talked and slowly walked and said like in a weird “calm” voice that it’s very very important that i remember that that glass is her specific glass. 
she also sometimes just repeats the same sentence when she’s in this mood. 
what is this? i don’t mean to diagnose her with anything i was just wondering if anyone knows.
