It conveys various meanings:
work: ‘caring for’ someone – undertaking the physical or ‘tending’ tasks they might need
and
love: ‘caring about’ them – feeling affection, liking, love, wanting to protect
Care by means of attending to a loved one's or a person's health needs (preparing breakfast, helping in the toilet, administering medicines, etc) is very difficult and requires love and compassion
