Hey Rebecca!

Thank you for genuinely caring for your patients and treating them with humanity. I work in health care settings and have also seen this callous attitude time after time. It is very difficult to not get caught up in the negativity. My one suggestion would be to find sources of inspiration (ie people behaving thoughtfully and compassionately) outside of your work environment to connect with in some way. It is easier to believe in something (in your case compassion) when you see others committing to it also.
Also if you need to find some compassion for your coworkers,maybe consider that you don’t know why they don’t have compassion: maybe they don’t know how to set boundaries and therefore are wary or maybe they were unfortunate enough to face negative consequences for their compassion and now avoid going there.
