Is it bad that bc I tend to every once of my children's needs. That I have not yet been able to take, time to brush my hair? I haven't brushed it in 2 weeks. I keep it up in a pony tail all the time bc its hot. And bc my son is starting to grab it lol. And I find myself not taking showers for days. I wish I had a break though. Lol. I need time for me.
