Either whooping cough or the worst case of a chest cold ive ever heard of

Sunday morning I woke up with a tickle in my throat. Now Tuesday morning, I am coughing so hard I throw up. What do I do I don't get sick so I don't know what to do?! But I'm miserable. I can't sleep and breathe at the same time . I'm literally having to sit straight up to be able to breathe and I cannot sleep like that. My lungs abs and sides of my belly are hurting so much every time I cough. Do I make an appt with my regular doc? Do I see my OB? Do I go to the ER?

I got sick with a chest cold about 6 weeks ago and just like that time I started taking meds as soon as I felt it , but even at its peak it wasn't this bad, lasted about 10 days. I can't imagine my cough being worse than this. Like if it got any worse they'd probably need to put me on a machine or something. My mom is not answering my texts and calls to tell me what I'm supposed to do. Please help.
