So sorry to hear you're having trouble. Sadly, there is no way to do this from Acrobat. Assuming you have "Copy selected text into Highlight..." checked in your Acrobat preferences, you'd then have to manually copy and paste all the content from each content into a spreadsheet, word doc, etc.
If you didn't have that box checked, and thus your comments don't contain the content of what you highlighted, you would actually need to go back and reselect each bit of text and then copy and paste it into your word doc (or where ever). It's a pain, I know.
For what it's worth, Bluebeam Revu has this feature. You can export your comments to a CSV or PDF and then do with them whatever you want.
