Do you know the feeling of being completely overwhelmed with emotions to the point where you know that if just one more thing is added to the whole mix you'll come completely unhinged?

Maybe it's just me. I've been in this place a few times in my life and it's always been when I make my worst decisions. I become needy and angry and scared and desperate and feel like I'm falling a part. I feel like I can't breathe.

What do you do? How do you get through this? What if I do fall a part, will I know? If I am about to go crazy I need to make sure my kids are taken care of. Are there warning signs?
