You first

I've been told that it is selfish to put yourself above others. I didn't take offense because I had to consider the age of the person who said it. They come from a time where it wasn't understood about the importance of self-care.

Self-care isn't selfish, its compulsory for a well balanced life. If your personal tank is on empty how can you be of service to others. You can't. 

It's okay to take a pause. To reflect. To make changes that are necessary. When all is said and done it will be just you with you. All those opinions you sought won't matter. Live a life with no regrets. That is all that will matter in the end anyway. <3
