<human>: Provide a brief overview of the text.

I am really having a hard time here, she means the world to me.  I have lost both grandfathers and a few friends, however, nothing will compare to this.  I am in my mid 20's and she is in her early 80's...I know our time is limited, and there is a chance that everything will be alright.

I received the call last weekend that she had suffered a stroke.  We had a streak of terrible storms and she had no power or phone (refusing a cell phone in the past - she now has one for emergencies).  It was extremely mild, I realize how lucky we are, and that once again, a bullet has been dodged.  We have always dealt with heart issues over the years and everything has always turned out favorable.  

After a stay in the hospital, she was released and I have been at her house ever since.  There has been no terrible side effects other than vertigo/dizziness from time to time.  An appointment with a surgeon is scheduled for early next week to evaluate Carotid artery surgery.  

My worry comes from the fact that it could easily happen again between now and the time of the surgery, or that there will be complications during the surgery.
<bot>: Grandma had a stroke during a power outage, even though we were VERY lucky, I feel like I am watching a ticking time bomb.
