I like the way you think, just some parts got me a little confused in what you meant.
But overall, nice reflection. There is this saying that I really like, I'll try my best so it makes sens in english: "Fill your glass first and only give what overflows". I think this can relate to your post: To think about yourself first don't mean you are selfish all the time, sometimes when you give your are not being selfless, but you a sacrificing yourself, most of the time for something that you only think you need.
Thanks for sharing!

You're right. There's this saying that self-care is not selfish. You can't give what you don't have. I think that when people understand this, it becomes more meaningful and we give better
