Maybe for kinds of food that you (and even maybe me) would miss?
There might be some people that you would miss talking to?
Is there any media you consume that didn't came to an end, and you want to know how it ends?
Maybe you'd miss your pet, if you have any?
I'm just trying to think of things that could be valid, but I know that depending on how tired you are, things can lose their value. I know it sure feels like shit when nothing feels worth living for anymore.
I've heard that the right thing to do would probably try to rest.. and honestly, sometimes taking some time to yourself, even if it's just sleeping, can be actually really healthy.
I hope you find a good reason to stay.
And even if you don't, that at least you don't leave this world in pain.
Wishing you the best out there
