Disability within the media

Within the clip (7:14-12:00) I picked up on several things that shows signs of bi-polar:

1) Can't come to terms with illness
2) Spending ridiculous amounts of money, money that she doesn't have
3) Stacey says that she is 'normal', and is implying that her mother, who also too has bipolar, isn't 'normal'
4) At the end she repeats she is 'normal', by saying this she is indenial that she has bi-polar, and wants to make herself believe she doesn't
5) Excessive drinking
6) Up and down mood swings

I was reading the comments on the clip, and people with bi-polar said that Eastenders portrayed the disability perfect. As it is a sensitive subject to touch base on, they must have gone into a lot of research to enable them to portay Stacey in a non-offensive way.
