freaking out about preeclampsia

Has any mommies had preeclampsia? I was pre diagnosed with it yesterday and just waiting for test results from a 24 hour urine sample to get the full diagnosis and treatment. What's a typical treatment and how far along we're you when diagnosed? The doctors kind of left me in the dark yesterday after I was done being monitored so when I dropped off the urine sample today I asked a million questions to the lab nurses and she finally told me what I was being tested for and why they needed the sample and that I am on modified bed rest until I get results in.
