Site Down, DNS Not propogating. Help!

Usually the nameserver change at the domain registar can take up to 24 hours to apply the changes.

I see the new Cloudflare nameservers.

But, you have the issue with the redirect loop, I assume due to wrongly selected HTTPS (SSL) settings at Cloudflare SSL tab.
What SSL options have you got selected at Cloudflare dashboard?

Or, may I ask if you have had an SSL certificate for your domain/website before moving to Cloudflare?

Regarding Bluehost, here is the tutorial how to connect custom domain at Cloudflare with your Bluehost hosting provider:

May I also ask:

  1. Or, maybe you manage your DNS records for your domain at Cloudflare?
  2. Or, the Bluehost is an integrated hosting partner, so you would need to apply the changes using their interface?
