I mean, it's pretty obvious free will is an illusion if you stop and think about how the universe functions. If everything is governed by physics, then why would we be special? In order for "true" free will to exist, it is necessary to exist outside the realm of physics in order to make decisions without said decisions being affected by the chemical and electrical signals in your brain. You have to be able to make choices that won't be influenced by the physical world, which, afaik, there is no evidence for.

However, even from a philosophical standpoint: if we rewound time to the last major choice you made, so that you could make it all over again, would you do anything different?

Keep in mind that we rewound time and you don't have any new knowledge that you acquired after originally making the choice.

Personally, I can't see a reason why I'd make any other choice. As such, that seems like a much larger existential crisis in the same vein that you should be concerned with.
