Hi @Polly48
 
Sorry to hear you had a rough day. The following instructions should be able to lead you to your drafts:
1) Click on your username in bold on the top right of this page (It says 'Logged in as...')
2) Under 'My settings' on the right hand side, there is a heading that says 'Autosaved drafts'
3) Click on the title of the post and it should open a text box for you to continue writing, as you would with any other post.
 
Let me know how you go!
Nik
