Need advice or kind words

Yesterday I felt off at work and had nurse check my blood pressure and it was 158/86 (my normal is 120/70) I called my doctor and since I had appointment today anyways they told me to just go home and relax. Well I'm back at work today just trying to take it easy till appointment and I'm just feeling off again. So basically I'm worried I may have preeclampsia. I'm 20.2 weeks today. I've read horror stories about this condition and am beginning to fear for my baby and myself. So if anyone has had this happen before and continued with having a healthy baby please share. Or if anyone just has some prayers they can send my way.
