The letter ruth had which she thought said help me was the letter about her divorce, jay say a letter in the hands of someone taking ruth away that was sectioning papers.
aparently this is ruth finally having a manic episode and is going to be diagnosed as bipolar (having had a previous depressive episode), she probably was on antidepressants and went off them, and now having a manic episode, then again antidepressants arent usually prescribed for someone who is bipolar, only if they are in a bad depressive episode.
with regards to kirsty i was hugely wondering what she did with her daughter, she probably didnt leave her in the house, like next episode we will find out that she sent her to a friends of something else convinient like that!!
