Let's tackle some of the main obstacles here.
1) Loved ones dying.
They do now, you're just not there to witness all of them die, but you will witness at least some of them die. There's no escaping that. I feel you would eventually create some sort of personal ritual which you go through to remember the people you love forever.
2) Evolution.
I don't get your point here. The fact that you're immortal doesn't make you reclusive. You should be able to keep up with these changes (except for the physical ones). But if you are the only one immortal, you will probably be held as a go (or a monster) anyway.
That all said; being biologically immortal doesn't mean you can't die. You can still bleed out, drown, etc.
