If you have an older sister who plans the agenda for vacations in your family, cares for your parents or grandparents, and organizes family holidays, she may have "eldest daughter syndrome." A licensed family and marriage therapist, Kati Morton, explained the eight "symptoms" of this term in a viral video on TikTok.
These symptoms include feeling responsible for others, overachieving, anxiety, people-pleasing, and placing boundaries, feeling guilty, having difficulty with adult relationships, and feeling resentment towards siblings and parents.
