Hi Lila. I moved your post to the help forum.
The simple answer is you can't.
You can edit a post up to 15 mins after you first post but that's it.
Only Mods and Admins can edit or remove posts then - and it's pretty rare of us to do that unless there's good reason.
If you still want to follow this up you can PM me, or another Administrator or Mod
