1st Time Ablation: How to calm my anxiety?

Hello fellow heart warriors. I have hypertrophic obstructive cardiomyopathy. Had open heart surgery in April of 2021. Long story short, now have arrhythmia and they aren't able to distinguish if it is SVT or V-Tach. I'm scheduled to go into Mayo in June for EP study and ablation and possible pacemaker. I'm extremely nervous now because they said I have to stop my beta blocker for 5 days prior to surgery. I was already having a lot of anxiety about going in for this procedure since they will be inducing a tachycardia event while I'm awake. It's all so nerve wracking. My mental health has begun to decline and knowing I'll be without my meds for 5 days is scaring me bad. How do you handle this? I've reached out to the provider to make sure he wants me to be without the beta blocker for 5 days. Even so, this anxiety is so much. I'm 48 years old. Had the open heart at age 46. My condition is congenital. I just want some normalcy in my life. My symptoms are so bad now I'm no longer working or driving. Can't even clean my house. Walk from bedroom to living room and symptoms amplify. I joined this support group because I'd like to make some friends and also hopefully help others. TIA and much love. ❤️
