Does anyone feel like they are doomed to be alone for the rest of their lives? I have been epileptic pretty much since I was an infant.

I was born with a ventricular brain aneurysm. Which caused Hydrocephalus. The brain surgeries for both(six by 9yrs.-old, none for the past thirty-five years) of them, caused Epilepsy.
I was married(1992-2000). I was engaged to be married(2002-2007). I am in relationship(2007-present) with a woman at present. But I always fear ultimately dying alone, due to one of my health problems.
