Blog Post and Comment Page exactly the same

This is driving me nuts and I want to be able to fix it, but I’m not really sure how. What is happening is that Google is indexing my blog post and my blog post with comments as separate pages…but the pages look exactly the same. Here is an example:

https://foreversinging.com/articles/singing-success-review/comment-page-1/
https://foreversinging.com/articles/singing-success-review/

Both pages look exactly the same..and it is annoying because Google keeps deciding to show the comment page in results rather than the actual, real page. Is there anyway to fix this to where I don’t have that separate comment page?
