i said it once but i’ll say it again
self care is Literally taking care of your self. it’s about doing what is good/healthy for you, even if it sucks and is hard to do
how capitalism turned it exclusively into buying things is not surprising at all but that’s Not what it is (although sometimes they can overlap as doing fun things is part of taking care of yourself)
self care is never selfish if it’s what you need at the moment.
