When people hear "self-care", they think that it means that you indulge in yourself by treating yourself something expensive or the like. This is not necessarily true. While I don't mind treating myself to things like a pedicure or clothes/jewelry, self-care refers doing those things that will meet your needs not only physically, but spiritually, emotionally, and mentally as well. Self-care is an act of self-love, the most important love there is, a precursor to a romantic love in my opinion.
The activities that you do for self-care could be anything that takes care of your needs. For me, music, writing, and exercise have been so helpful toward my own self-care.
Remember to love yourself always. ♥️♥️♥️
