I'm sorry you're going through this!
Huneygirl07 gave you some good tips - take some slow deep breaths, in through your nose, out through your mouth then hold the exhale.
Have you had these symptoms before? When was the last time you had a full check up with a doctor? I would reach out to someone you trust and talk to them about what's going on.
Honey, it's probably a panic attack. Take some deep breaths and try to relax. If it doesn't get better or gets worse, trying calling to speak to a nurse at your local ER.
