Fiona Monica Gallagher, aged 28, is the eldest of the Gallagher children. Because of her mother's absence and Frank's neglect, most of the responsibility for child-rearing falls on her shoulders which forces her out of high school in her junior year. Fiona works a few dead-end minimum-wage jobs to support her five siblings. Though often stressed and exhausted by her responsibilities, she always performs them. Prone to selflessness, she sometimes needs to be reminded to look out for her own happiness. Even though Fiona wants everything under control, she enjoys a little bit of chaos once in a while. Fiona often comes through for her siblings and loves them dearly.
