"Hey everyone, hope you're having a great day! Just wanted to share a quick reminder that self-care isn't selfish, it's necessary. Take a few moments today to do something that brings you joy or helps you relax. Whether it's reading a book, going for a walk, or simply taking a few deep breaths, prioritize your well-being. Remember, you can't pour from an empty cup! #selfcare #mentalhealth"
