Hey Ciera to keep this simple you can try to remember this when reading these type of phrases and find yourself stuck. Each one of these endings is almost like a code or hint for you to understand and fill in the blank. A = To, so you already know the first half, A is to someone, the Second part in this case is MI, which means ME. Just remember to read the ending on this type of phrase as it will help remind you what type of stiuation you are in.
a mi - TO ME
a el - TO HIM
a ella - TO HER
a ellos - TO THEM(BECAUSE OF THE O IN ELLOS IT REFERS TO A GROUP OF MEN OR MEN AND WOMEN)
a ellas - TO THEM(BECAUSE OF THE A IN ELLAS IT REFERS TO A GROUP OF WOMEN ONLY)
a ustedes - TO YOU GUYS(USTEDES IS A WORD DIRECTING THE PHRASE TO A GROUP YOU ARE SPEAKING TOWARDS FOR EXAMPLE)
