Hi
Your experiences does indicate symptoms of anxiety disorder. It is important to rule out any physical health reasons contributing to this like any
thyroid, anaemia or even any use of alcohol, smoking or other substances. Any ongoing stress or threat perceptions need to be explored & addressed. If the impact is significant I suggest you consult a psychiatrist. If it is mild, start some relaxation exercise, yoga, meditation, good sleep hygiene & start being present to moments of anxiety & carry on with your work without fighting with anxiety symptoms. Best wishes
