I dunno if my computer is just horrible or if I'm download something different, but when I try to download Flash it says it will take "about 42 days" to complete. Is this natural?

Do you have a screenshot?

I'd have to wait until tomorrow to get my charger to re-charge my laptop and take one :/

More often then not, the download times for programs are unrealistic. I doubt that your download will take 42 days to complete. However, on the off chance that it does take 42 days, maybe you could use the time to inspect why your computer is so gosh darn slow! haha

It may also be that the application you are downloading is flawed. In order to minimize this, i would recommend only downloading files from trusted sources that you know provide functioning applications. Adobe is obviously a trusted site seeing as they create Flash and I would suggest downloading it from their website before trying to download it anywhere else.

I think it would be a good idea to delete that and try another download. >.> And, don't use torrents.
