Meanwhile, you can try some grounding techniques, deep breathing to help put your mind and body at ease.

Health Tips
Please don't take unsupervised anti anxiety medications, as it can do more harm than good. Also, a bottom line I tell all my anxiety patients, stay away from Googling your symptoms or self diagnosing. Seek an expert opinion.
