Welcome to Healing Well and to the Aniety~Panic forum.
I agree if you have medication to use, please use it when you need it. There is no shame in needing meds.
IMO I would like you to follow thru on the cardiac work-up.
Atrial Fibrillation (AF or A Fib) is a relatively common heart disorder. AF is an irregular, rapid contraction of the atria. When you feel dizzy or lightheaded take your pulse, if it is fast and irregular you may be in A-Fib.
In AF, the atria beat out of rhythm with the rest of the heart. In fact, the atria may beat as many as 400 to 600 times a minute during AF, compared with a normal 60 to 100 times a minute.
Although some people with AF experience no symptoms, many experience a wide variety of symptoms, including palpitations, fatigue, dizziness, shortness of breath, and chest pain. So it is important to recognize the symptoms of AF so you can discuss them with your doctor.
I am sure your Doctor explained these sx to you so this is probably just a refresher
Keep posting as we are here for you.
