I have the same problem with this as with teleports. My consciousness will cease to exist so it can continue somewhere else.

If consciousness is universal and you are just “attuned” to this body, maybe you can be attuned to another 🤷♂️
I might be to materialistic to get that.
There are many reports of people describing a feeling of being a part of something greater and feeling like “one” with everything when they have out of body or other meditative, psychedelic or religious experiences. This could suggest consciousness is a field we tune our antennas (our bodies / brain) to. So maybe if one body is gone, you could somehow eventually tap into this field and regain consciousness of your previous senses and experiences. That would require some insane tech though and advancements in so many areas.
It definitely sounds comforting. Maybe the advanced tech and other people's experience will show us how it really is.
