Why am I so tired?

The past two or three weeks have been hell for me. I'm totally exhausted every day. It doesn't matter how much sleep I get because I still wake up tired.
Usually after I get home from work and pick Lillianna up at school,I fall asleep on the couch for 2 hours before I make dinner. It's not that I'm just a little sleepy. I can't stay awake. I close my eyes for a second and two hours go by.

Today I had to shower and go food shopping but I kept falling asleep for 10 minutes or so and just when I thought I'd head into the shower,I'd have to nap again. I didn't shower until 4pm!

I googled the side effects of my blood pressure med that was increased from 10mg to 20mg several weeks ago and fatigue is one of them. I think I'll call my doctor on Monday. She had me take a blood test to check what kind of anemia I have but I never heard back from her. I think between the anemia and bp med increase I'm always one second away from napping. Not a good thing at all.
