I've got an aneurysm too. They found it 4 yrs ago looking for the source of mind-numbing headaches. It has nothing to do with the headaches, but it sits there approx. behind my right eye--about 3.5 mm of possible death. At least that's how I felt about it for a long time.
After 4 yrs I'm lots less fatalistic. I've found a fabulous, cutting edge neurologist/neurosurgeon who will look the situation over again via angiogram this December, then check again in 2 yrs.
Everyone's different. There are options in treatment. For me, the primary goal always was to find a doctor I could trust with my life. Doesn't mean i'm off the hook now, just that he & I are partners in my aneurysm healthcare. I feel shed of a good 75% of the stress. I know to keep my blood pressure low and not to get constipated

, stuff like that. so once again knowledge is power.
You'll be soooo much better off after your angiogram which, BTW, ought to be not a big deal. I'm a curious 8 yr-old with things like that so my questions throughout offset any panic. You're awake & feel practically nothing except the initiating prick.
Hang in, come back, ask questions. This is a *great* place to be!
