Meltdown

Feel like the worst mother in the whole world - had a meltdown this morning all because I was running late, and then I was running later, and then I was running so late I just wondered if I should give up and go home. Ended up stopping the car on a quiet street and just screaming so loud I scared the kids. :( Not feeling like I'm doing the "best I can" at the moment. Feel like I'm sliding down that slippery slope of doing the worst I possibly can. Don't know what I need right now to pull me out of it.
