Your feed at http://www.currentlyrachel.com/feed/ is operating just fine, but it’s not valid: http://validator.w3.org/feed/check.cgi?url=http%3A%2F%2Fwww.currentlyrachel.com%2Ffeed%2F
Those errors are typically caused by a malfunctioning plugin or theme.
Try deactivating all plugins. If that resolves the issue, reactivate each one individually until you find the cause.
If that does not resolve the issue, try switching to the Twenty Fifteen theme to rule-out a theme-specific issue (theme functions can interfere like plugins).
I gave all of those things a go (deactivated all plug-ins, switched to the Twenty Fifteen theme) and it still told me my feed was not valid?
Does this take a while to update, I only tried this for a few minutes?
Otherwise I’m really not sure what my issue is.
I have also contacted my webhost who cannot provide me with an answer.
Since deactivating my plugins, I now cannot use Jetpack after reactivation. It says my site is inaccessible.
One other thing to try for fixing the feed:
Try downloading WordPress again and delete then replace your copies of everything except the wp-config.php file and the /wp-content/ directory with fresh copies from the download. This will effectively replace all of your core files without damaging your content and settings. Some uploaders tend to be unreliable when overwriting files, so don’t forget to delete the original files before replacing them.
For Jetpack, I recommend asking at https://wordpress.org/support/plugin/jetpack#postform so the plugin’s developers and support community can help you with this.
