Paralyzed by fear!

I got a positive pregnancy test on Sunday and have been testing daily, sometimes 3 times a day, just to make sure that I am still pregnant. I have been ttc #1 for over 6 months so I am used to hope and later disappointment. But now I finally got my prayers answered but why am I not rejoicing? I am terrified about losing this baby, my dh and I have only told a couple of people because of my fear. I have read countless stories on Glow, babycenter. com and other site about miscarriages, chemical pregnancy and etc that the fear of experiencing the same has literally paralyzed me from enjoying this mirecle. dh and I have started praying, I have turned to praying whenever my mind starts wondering. I can't even picture holding my angel because of fear. I am driving myself, husband and best friend mad by constantly worrying. I am in thr Army and went to see my primary doctor yesterday and he was worried because my blood pressure was so high. I had a blood drawn to confirm my pregnancy and now am panicking waiting for that result worrying about it being negative after over 10 at home positive test. God how can I get control over my fear and worries?
