Hi there and welcome to Apple Community Discussions...!
Sounds like you have an early MacBook 13" 1.83 or 2.0GHz CoreDuo that may have shipped with a Tiger 10.4.6 system, or so. Do you have Leopard 10.5.8 in it now, or is it still working with Tiger 10.4.11?
I found some information that you could attempt to extract what you can make use of, and try; since you are in an emergency situation and essentially have a hardware failure of some kind or another that a repair could fix. (Or a newer computer with less time on it.)
Here's a support discussion of a similar topic:

Most of this assumes you have a system to put on a USB, perhaps a backup or clone, and a way to install one on a USB from DVD installer, etc, and so on. Others may have been more creative.
You may be able to share another computers internal optical drive
when the other computers main combo or superdrive has failed.

What other computers do you have on hand? Cables? An Ethernet cable?
Or an Odd double-ended USB cable that could be used by a kid as a jump-rope?
Two cans and string? LOL silly enough, huh.
How's the total installed RAM total capacity? How about hard disk drive free-space?
Hopefully something can be done to get your old MacBook up on wobbly legs.
Good luck & happy computing! 🙂
