Hi godftamm,
Welcome to this site. There are many people on here that really care and I am sure they will be replying to your post shortly. I am sorry you have to go through with surgery, my AN was removed from my 8th cranial nerve, but the doctors told me it was very deep inside. My youngest son revealed to us in his first year of college that he was very depressed etc. We pulled him from the college brought him home and got him counseling. They had him on medication for a while. He was diagnosed as bipolar, but he has really worked through most of his symptoms. I wish I had better advice or information about how to help you, perhaps other members will weigh in. But I wanted to share with you, that you need to take one day at a time, and one thing at time. Deal with your surgery first and the recovery. You can focus on your depression once you have recovered from your operation. I hope all goes well with the surgery. Stay in touch with the members here on this site.
God Bless.
