How can I export all of my own answers but only my own answers without any comments but together with the questions into a text document?
You can build your own App to do that. With Answers on Users you can query for your ID in a given site. These are your first 100 answers on Stack Overflow:
I see that you have 99 answers and the result of the query has the following at the very end:
"has_more":false. With this you'll iterate through all pages when there are 100+ results. As pointed by Dave Chen bellow, you can add a filter to retrieve the body of the posts.
