Yeah, same. I can sympathize with the fact that it sucks to have to be the grownup in the situation and it is really hard to manage your anxiety when you have to... but that line is evidence of such a completely broken conception of what is going on in this situation: justifying herself aggrievedly as if she thinks the reader should take her side and agree that her feelings are just more important than normal people's and everyone has to experience them with her AND LIKE IT and children failing to appreciate this are being selfish. Wow.
