fatigue or laziness...

Today, I spent almost all day in bed to make up for all the activities going on last week. I slept, watched tv and ate. That's about it. Nothing productive at all. My daughter begged me to take her anywhere, even the stationary store (she hates the stationary store). All of her friends are busy. This weekend the time changes. I know I just don't adjust well to changes. Hopefully I will be able to last at work. I always seem to have that problem when the day gets longer. I took all my usual pills and then some. I feel swollen. I have been taking my diuretics, but I don't know...when I eat I feel like I have bad heart burn. If I don't eat I'm tired. Well my daughter is having her cycle for the month. I haven't had a period...for more than a few years from the chemotherapy treatments. It is so weird when I have to buy stuff for my daughter, so many choices, so many different brands. I feel like my body is trying so hard to have a cycle when my daughter does, but it just doesn't happen. We all get cranky, swollen and just feeling like crud. I know my husband understands that I battle fatigue everyday, but today, I almost felt like I had become lazy. How does one really tell the difference between fatigue and laziness?
