Error causing my RSS Feed not to work

I signed up for Bloglovin’ in order to gain followers and to keep my followers up to date. However my posts don’t get updated on my Bloglovin’ page and they have told me it is because of an error that I have on my RSS feed. So I checked the RSS Feed and this is the error that I get:

This page contains the following errors:

error on line 31 at column 25: Extra content at the end of the document

Can someone please explain how to isolate and correct this? I’m not very savvy about coding or anything like that and at best I have a minimal working knowledge of HTML and CSS. Thanks in advance!!!
