Hi Dori,
If it is only your posts you want to see replies to, click on the profile button at the top of the screen. This will take you to your profile, where your personal information is. At the bottom of that information - under Additional Information is a link that says Show the last posts of this person. Click that link, and you will see all the posts you have made, in reverse chronological order. Click the rightmost portion of the link there, and it will take you directly to your post, then you will be able to see all posts after that.
Let me know if you need additional help, I would add screenshots but I need to leave home in a few minutes.
