how do you say i care about others than myself?
Actually, the English is probably "I care more about others than myself?"
There are many ways to convey this idea, depending upon the vocabulary you have studied! You should always try to use the vocabulary you have learned first. Then you need to know how to use the dictionary well. If y ou don't have a good English/Spanish and Spanish/English dictionary, invest in one, or there are lots online.
Now, if you looked for "to care for" one verb (and there are others) would be "cuidar de" so using that, you might say: (Yo) cuido más de otras personas que de mí.
