Anxiety attack

I went for my booking in appointment yesterday and my BP was almost high but still in normal range. Midwife said she wasn’t worried at all and we’d been talking about previous miscarriage and it was a strange place etc that’s why it might be high. Since then I’ve had major anxiety about whether baby whether it’s ok. Started to have panic attack driving home on school run but managed to control it. I’m 9 weeks exactly tomorrow and this is when I had the miscarriage last time. I’m wondering if the anxiety is causing my higher bp? So far no bleeding or cramps like last time which is keeping me positive. But every time I don’t feel sick I’m in a panic. They don’t give me a scan until 12 weeks and I can’t wait in this state like this until then. Am I going nuts?! If I see my GP will they say just to chill out?!
