What can I do in this situation? How can I resolve this?

It sounds like you have been experiencing nausea and vomiting due to anxiety and possibly the iron supplements you were taking for your anemia. It's important to consult with your healthcare provider to address these issues and determine the best course of action for managing your symptoms. In addition to medication, consider exploring therapy options which can be beneficial in conjunction with medication for anxiety. Don't hesitate to reach out to your pharmacist for further guidance on your medications and potential side effects.
