I am so sorry you are having these anxieties right now and hope the surgery goes well. But more than that, I hope the time leading up to the surgery goes well. For how to focus on the now, maybe allowing yourself to ask for reassurance might help. (even if it is "more than what is humanly possible."

) What you are feeling is such a real anxiety and though the outcome of the surgery might not be obvious beforehand, (though I am sure it will go fine), what is going on now is just as real and difficult as the actual surgery, maybe even more so because all the anxieties are on you. You
do have some control over that, maybe T can help you feel safer with those fears about surgery. In a way it is easier to be knocked out and leave it in other people's hand than to go through the buildup to surgery, at least I feel. You are doing the hard part now, and you don't have to be alone through this, you have us on here. And i hope you do go back to T and tell them this..
And yes Klonopin really does help, if taking meds is not something that is an issue, hehe
