Severe Ozempic Side Effects

I am new to taking ozempic and just started 5 days ago. The prescribed dose was 0.5 mg and I have been so sick ever since I injected that dose.
I'm experiencing nausea, dry heaves, and most unexpectedly, severe anxiety. I feel like I'd like to crawl out of my skin and can't wait till this drug clears my system. I can't eat, but I know it's not healthy to totally forgo essential certain vitamins and minerals. I snack on pretzels because they are bland and have salt.
Has anyone else had an extreme anxiety and sickness response to starting Ozempic?
