Hormones out of control, what to do? :( **URGENT**

I'm having HORRIBLE anxiety, feeling nauseous hot, scared. I'm on my ovulation week, last month around the same time I felt the same but it's now escalated. I don't do caffeine, or anything with sugar. I'm shaking with anxiety. I've been calming myself down, but in scared because this keeps happening. I NEVER have anxiety about anything I set up an OBGYN appointment on the 28 but I don't know if I should go to the hospital or something now. I need ANY advice I can get please. I don't feel like myself
