Definitely the rest of my life.
This absolutely depends on conditions on the island.

You can survive three minutes without breathable air (unconsciousness), or in icy water.
You can survive three hours in a harsh environment (extreme heat or cold). You need shelter!
You can survive three days without drinkable water.
You can survive three weeks without food. But, many people have gone for over 40 days during fasting and have survived.

I dread to think what state your body is in by that point, it has to be consuming itself to keep going.
You CAN survive, but the larger question is would you WANT to survive?
I’m assuming “can survive if you get immediate medical treatment at the end.”
This guy went 382 days, but did have water and vitamins, just no food.
Knowing how strong and smart I am I’m going to guess about three hours.
To quote xkcd, “On one hand, every single one of my ancestors going back billions of years has managed to figure it out. On the other hand, that’s the mother of all sampling biases.”
And ok, sure, the more recent ones haven’t had to rough it, but if you go back just a few generations you get to someone who actually knows something about something. Still, I think I could suss out at least enough to keep going until I inevitably got injured or sick or mauled by a wild animal.
That said, I’m very aware that this might just be unearned and unmerited arrogance, like the guys who say they could take a point off of Serena Williams on the tennis court.
Less than six hours, I have diabetes.
I’m so dead.
I do not have the energy for this, I’m depressed as fuck, anxious as fuck, pre-diabetic (I think) and I would just feel so weak and crumble and die. My body starts shaking the moment I process the previous foods. I would probably think its a weird dream and try to “kill myself” to exit the dream.
Very Very Dead.
I have zero survival skills even if my depression gets magically cured.
Humans aren’t meant to play this game solo.
I’ve got rudimentary survival skills that could keep me alive in the wilderness on the NA continent. But in a resource-limited island, it would depend on what’s available. Beyond that, this question is too open-ended to answer.
If there is clean water and some food I can figure out how to harvest relatively easily then I like my odds.
Assuming it’s not an Arctic island. Then I have until winter.
Assuming it’s like a small-ish tropical island and i’m the biggest predator around, with plenty of fruits and also a pond with fresh water and fish i can eat, i’d say i’ll die in the middle of the first night from hypothermia because i can’t tolerate cold.
it would be just like Minecraft, so I’d make it till nightfall until skeletons and spiders murdered me
At most until my medication runs out. From then on, it’s going down the drain…
When I go ?
If there is a source of clean drinking water? I would have a shot tonCastaway it…
Assuming it’s a tropical island, I think I’d do well enough.
If it’s of any size at all, there will be fresh water, and in any case, it will fall from the sky soon enough.
Even if there’s nothing to eat on the land, unlikely, there’s plenty in the sea.
Making fire would be my first and most difficult chore. Even guys that are practiced struggle, but if our ass is on line, it’s amazing what we humans can get done.
Much depends on what gear I have when I get there. Not having any sort of knife would be hell. Having cloth is a big deal.
