These are good descriptions of being overwhelmed. It happens to me if I have to deal with too much bright light or loud noise, when I'm in too hot of an environment, if I socialize too long, if I have to drive too long or focus too long on certain mechanical tasks like painting, putting sealant on my deck, and the like. It's like I wake up in the morning with a certain amount of ability to tolerate various types of stress and each taxing experience depletes the remaining amount. I have to sort of budget how much stress I take on and pace myself.
