I am working three 12's, taking two or three graduate classes a semester and have 3 children still left at home. The youngest is a three year old. I am at the end of my second year, half way there. I am totally overwhelmed and feeling burnt out. But I'm hanging in there. Be prayerful and decide if it's what you really want and if it's what The Lord want for you. If it is, you'll get through it. Hang in there, be prayerful and take it one day and assignment at a time!
