hooray for emotional breakdowns

I'm supposed to be outside right now, helping to manage a garage sale we are having. Instead, I'm inside the house, hiding from everyone because I was close to falling apart. I don't know what the deal with me has been lately. I'll be doing perfectly fine and then I reach a certain point and I become exhausted, irritable, snappy and wanting to crawl inside my shell and hide from the world. If I don't get to, I start crumbling. I snap, I cry, I get hyper emotional and negative towards anything that comes my way. I seem to have no control over it. I'm wondering if it is from being around the two boys I work with. Nine hours a day, every day with two extremely active, easily bored, quick to cry, complain and fight little boys. I think after this summer I've finally reached my snapping point. I spend next to no time by myself. This is a huge change seeing as most of the last few years I've spent a ton of time by myself with the CHOICE to see people. I don't like being around people unless it's my decision to see them. I come home from work and I see my boyfriend or my family or I get on facebook and talk to people. I didn't realize that I was burning myself out. I need time alone.
