Deleted Code in Text Widget in Oxygen

I accidentally deleted a text widget by not putting it in the “safe zone” when moving it around. The code that was in there is now lost and now the layout is all messed up.

It inherited this page from someone and now I cant figure out how to get the left and right sidebar (social media and newsletter) back in their places and the main body to feed the news page. Its all skewed to the left!

Please help!
