Is it wrong for me to think I'm immortal?

After many, many long hours of thinking about life, death, and what the world would look like without me (not in a suicide way), I've come to the only conclusion I can: I must be unable to die. As I've thought about it, I can't possibly imagine life after my own death, which then brings me to being decidedly unable to die. If my "life" is my perception, and my "perception" ends, there isn't even a void or anything, it just ends. So since it hasn't ended, it must not be ABLE to end.
I don't really think of it in a negative or positive way, it just seems like the only conclusion to "perception" is NO conclusion. No cutoff. Or at least, not one I understand or can imagine.

Is it wrong to feel this way? I don't really fancy myself a philosopher, and I know it's at least somewhat narcissistic, but if I were someone else I think I'd also draw this conclusion.
