Like many of us, I can go from 'relatively ok' to 'overstimulated/overwhelmed/almost melting down' very quickly. It's almost always brought on by some combination of fatigue, needing to focus on a task, and some kind of noise I can't control, although sometimes it can be brought on by things not going according to my plans or expectations. I'm in a long-term relationship (18 years) and we have a 4-year-old daughter. My partner is willing to step in and help, or just be understanding, when I am at the brink of being overwhelmed, but he has asked me to indicate somehow that I'm at that point, and I can't figure out how I would do that since I don't usually realize that's how I'm feeling until much later -- and he has a hard time telling, too. I'm wondering if any of you have developed the self-awareness to notice when you're reaching the point of being overwhelmed, and whether you've been able to somehow communicate it to others (a word, a gesture, anything). Would love to hear them, if so.
