Revisions received, time to get to work!

Okay...so this is me.  Stuck between plain terrified and stressed!  I've received my revisions from my editor and it's time to get to work. 
The truth is they are fine.  Five pages of notes and a genius action plan which is very concise and just what I need.  It tells me in one page and a few bullet points exactly what to change.  Some things are going to need a little thinking through.  My problem here is the time scale.  I need to give some indication of how long I think the revisions will take me.  Of course I want to do them all NOW.  But right now, I'm really not that sure how long they are going to take me.
Plus on top of all that - I'm scared.  There I've said it.  I'm scared I might do these wrong.  You know what I mean.  I'm a data nerd and posted on eharlequin about getting some stats, and someone gave me some.  I wondered how many people who submitted partials were asked for fulls.  Then how many fulls got revisions. Then how many get second revisions and how many go on to be bought.  I've seen lots of people on the eharlequin boards who've got to this stage and then got a big fat R.  So that's what I'm afraid of.  But on to better things...

Jenny Harper who I met at the RNA conference sent me a sparkly pic of my black dress.  Who said black was boring!  I was also invited to join an email group for Writers Scotland which seems very informative and supportive.  And last but not least I heard Rachael Johns talking about an online course on her blog and decided to join in, so Shirley Jump's From Good to Sold (I'm rubbish and don't know how to do things that link) now has myself, Rachael and Joanne Pibworth on board.  It seems we apparently are the bad girls at the back of the class, some things never change!  It's proving to be value for money already and it lasts until the end of August.  So I'm listening to what she says as I'm plotting my revisions.
Last of all, good luck to everyone at the Romance conference in Australia - I'm expecting FULL reports on your return!
