Is it anxiety or something worse?

So, I got a chest cold. I was coughing a lot, stuffy nose, lightheadedness. Im also on my period, which makes things worse. I've also had several anxiety attacks today. I got a sudden, dull pain in my right rib. My breathing is fine, but I'm worried it could be something worse. My upper back is kind of numb, also. And, my whole body is weak. Is this anxiety, or should I get medical help right away? I keep lookimg up things, and its not helping. My mom told me that my these weird feelings were from my period, but I'm not so sure.
