You can only be as good for others as you are to yourself. People you care for and love want the same for you, so be sure you are not making inappropriate sacrifices. Getting your needs met will sustain you and maintain your stamina and emotional stability. The people you care for are counting on your to stay well, so they can count on your for support. It's a job requirement and not a luxury. Be kind to yourself everyday.
I can go a long time taking care of someone while ignoring my own needs, but it always catches up with me. My body is designed to protect me, but if I continue to overload it without restoration time, it will take longer to heal from the damage I've allowed. I do not ignore myself and I never deprive myself of good food and sleep because my body works hard to keep me alive and it deserves more from me. Don't take your health for granted. Take long breaths, laugh loudly and rest deeply.
