she is feeling like chat backseating her sickness is making her self-conscious because it makes her feel like other people don't see her as an adult. She desperately wants to be seen as an adult and not some kid because it makes her feel worse about the whole "not getting married" thing. At the same time, she wants to be pampered and someone to take care of her because she feels vulnerable and needy.
Pretty much a massive woman moment of where she's inhaling 3 gallons of copium to say, "I'm an adult, I can do things on my own, I'm just as capable as my friends that got married" while at the same time she desperately wants someone to take care of her, give her compliments, give her food, and tell her that everything is going to be alright. Psychologically it's someone that has been an adult for a while but she perceives other people not seeing her as an adult, which makes her feel insecure, which is exacerbated by thinking about her friends "being adults" and getting married. Like many, she seeks security in those childlike experiences of having someone take care of her, which further conflicts with what makes her feel insecure in the first place. It's a sad conflict where she feels insecure and her method of feeling secure plays into what made her feel insecure in the first place.
