Can't Sleep

I slept for only 3.5 hours yesterday or should I say today. I slept at 3.30am and woke up at 7am to get my girls ready for school. I am not having insomnia but I just can't sleep because I nap for 2 hours with my children yesterday. It is also due to the stress of not earning the minimum income for this month that cause my brain to keep on thinking on ways to earn moolah. And to keep me awake now, I just gobble down a can of coffee!
