Aduh, I totally feel you lah, masa I pun ada situasi macam ni dulu, bawa anak sorang-sorang ke klinik memang penat sangat, and honestly it didn't always go smoothly pun, kadang I nangis dalam kereta lepas tu. Cuba call klinik tu dulu dan explain your situation properly, sebab sometimes kalau kita cakap terus dengan doktor atau nurse in-charge, they can make arrangements or suggest alternatives that the counter staff tak tau about. Jangan tanggung sorang-sorang ye, your emotional health matters too, please do mention this stress to your doctor as well when you go!
