Describe your main character from the perspective of the antagonist

My current story doesn't exactly have an antagonist. My MC is kind of their own antagonist, so I'll let them introduce themself.

My name is ....

I don't suppose it really matters now. It's going to change soon.

I've lived this life for a very long time. The year is 2374. I was born in 2232. But I don't have long left.

The doctor tells me I probably have a few months left. I don't have the heart to tell him he's off by a few months. I've got maybe a few hours left.

I only know this because, every time I get this near the end of a life, some memories from my previous lives start to come back.

I'm starting to wonder where and who I'll be in a few hours. My lives aren't exactly in order, so I could end up in any time. My last life was in the 19th century. And before that, I was a colonist to Alpha Centauri. We've still got several years before we'll get there, thankfully.
