In your own words. I've had moments recently where I feel like I could be having one but I'm unsure if they are in fact what's happening or how to describe them to DH to help him understand.
Eg trying to pack for a night away with 2 under 2 yesterday morning and when I feel overwhelmed my mind clouds up and I can't think straight and I start to feel this huge amount of dread and suddenly find myself saying "I can't do this" to myself. It takes a little while to subside but leaves me feeling drained.
