I know for a fact there are indeed (many) people just like her, but honestly she's hopeless. She's a disaster in the making (be it ending in a mental hospital, Overdose, suicide or maybe even murder) and really will hurt everyone close to her sooner or later (her family, boyfriends who dated her because they actually loved her and maybe even eventual children she'll have in the future). No one looking for a healthy relationship will want to keep dating her for a long time, at most they'll go out with her for her body and dump her once she gets too needy/annoying or crosses some line, and each time she gets dumped will make her get even worse. Therapy would help for sure, but it's not a miracle pill, she'd need to understand that there's more to life than having a boyfriend, to look for fulfillment elsewhere and to love herself more, but it's really not that simple or easy.
That said i feel like this shouldn't have the comedy tag. It has moe art and has the 4-koma format but that's it. Any comedy attempts fall flat because of how heavy the theme is.
