This is a question no one can answer.
Any answers will be guess work, supposition depending on your own personal reason for requiring to believe that there is an afterlife.
Some peole are inculcated from childhood and just continue with that belief unquestionably.
Some lose loved ones and are directed by charlatans to believe they will be reunited with them, quoting religious man made texts based on stories and myth ie zero proof.
The ONLY certainty is that we will all cease to exist.
If you have blood family who survive you (children, grandchildren )some of your dna will carry on and hopefully have a positive bearing on your future generations.
So a little part of you in theory will go on in our natural physical world.
Best wishes.
