callie tends to internalize her feelings - such as sadness and anger, guilt as well. so, with this little help from arizona (by just saying that pretty much everything is her fault) i am seriously conceirned about what she can do. not to arizona, not to anyone else in the world, but to herself.
Most people won’t admit it, or don’t even realize it, but caring for people takes energy out of you. Investing your time and attention making sure somebody knows that you love them and that you want to ensure their well-being can drain you. Mentally, emotionally, spiritually, even physically. Love people, but take care of yourself. Don’t burn yourself out.
