Vertigo

So today I woke up, got out of bed, and nearly crashed into my bedroom wall, then the bedroom doorframe, and then the hallway wall, all on the way to the bathroom. To say I was dizzy is the largest understatement! I waited a few minutes thinking that perhaps I had just gotten out of bed too fast. But nope, it didn't go away. I called into work and crawled back into bed. After about an hour of laying there watching the ceiling fan jump around (it was NOT on!), I finally fell asleep. I woke up a few hours later at least able to walk, but still not really trusting myself to drive, so here I sit. I feel horrible that I missed work (I HATE calling in!!), especially after two weeks ago when I missed nearly the whole week because of pregnancy complications, and last week when I needed an extra day off for my ultrasound. I'm glad the family I babysit for has been understanding about everything (it's not like I WANTED to miss work that much and have them out a sitter for awhile--not to mention we have bills to pay here!), but I can't help wonder what's going to be the last straw for them. I really love working there, and hate that it's been a rocky few weeks for me, and I am scared they will just say it's not worth the hassle. Here's hoping this is it for my craziness in the first trimester, and things settle down tremendously. It's really annoying.
