Hi (((Vikki)))!
I know that you are scared and you have every right to be!! - but this is something that should help you and get your heart more in sync, so that you will feel much better!
I know there is another post here that you had started yesterday re this and there are a lot of answers there - you may want to refer back to that.
Take care and best wishes, always - we'll be rooting for you!!
Hugs, Teri
