Why do you think Kitty drank so much?

I know there were a lot of housewives in that era that drank on the daily… but it was usually because they were very unhappy with their lives or had neglectful husbands. Kitty had a great marriage and a beautiful family who she obviously adored. She was also a natural nurturer/caregiver, so although she may have been tired from her responsibilities at times, she seemed to enjoy doing them regardless? It was almost therapeutic for her in a sense (which is also shown through her love of nursing).

Edit: never said that being a mom or taking care of everyone/working is easy lol. At the end of the day it’s obviously just a light hearted tv show, but I was curious as to why the writers chose alcoholism for her character in particular.
