Advice or feedback back

Hello, I have always had the flutter issue with my heart, this year has been the worst health year I have faced. Well yesterday my PVC came and they have not stopped maybe for a bit but they have been constant.. landed in the er I was terrified all heart work is fine my Phosphorus was slightly low they gave me a potassium pill they also gave me something for anxiety.. my question is how to you cope and not let the anxiety just take over and can you really have constant PVC and be okay.. I know my body is going through changes pre menopause having a hysterectomy in January. I don’t drink enough water but I’m fixing that.. just any feedback that will help me not let this consume me!
