Morning sickness help

Yall I am really struggling. I can barely eat, can barely sit up at work or home, I eat only when my nausea passes but it starts an hr after I wake up to right before I fall asleep at night. Being in the car gives me motion sickness. I left work early Monday Monday didn't go in Tuesday. I'm already off Monday for a trip i was supposed to take but cant because of motion sickness and I'm calling out tomorrow. I haven't thrown up it's just constant running to the bathroom and dry heaving. I'm in the process of getting a permanent OB dr. I don't know how to function. Any tips or miracles will be great.
