You have not been paying enough attention to your needs.
You need to focus on yourself so that you are in a better position to help those around you. Introduce mindful activities into your routine that keep life in perspective. Immerse yourself in things that bring you joy.
While your selfless attitude is compassionate based, consider if you are sacrificing your needs in the process. Are you sharing your kindness to please others, validate your value, or distract you from yourself? Consider what motivates you to give so much of yourself and seek a more balanced weekly schedule.
