How to fix a fight with mom?

Everyone knows that today is fathers day so my mom and i are very close but we always fight! Yesterday we were planning out what we were going to do for fathers day and so we went to the party supply store and bought trick candles (the ones that dont blow out) because it was gonna be funny for my dad to try to blow them out! So today we went out to eat with my family and then we went to the grocery store to refill the gallon of water (I HATE ice cream cake (but my dad LOVES it)) and we were gonna buy him an ice cream cake but I wanted to get a separate treat for me. And my parents said it was ok and I admit they are expensive and now I feel stupid because I was being a head! But at the end of checkout they decided to not get my treat!! WHAT THE HELL!! and I was ignoring them! So then we went to DQ and bought the stupid cake and went home so i locked myself in the bathroom and my mom was like are you coming for the candles? And I was like NO! and I came out and they were already eating the cake so I felt really sad because I really did wanna see the candles but I wasn't there so my mom just threw them away and I feel like I ruined Fathers Day for my dad!! (me crying)........ I picked up the candles and I kinda wanna make it up! So I have the candles but a REALLY MAD MOM! and she said she is never gonna buy me anything EVER again and I am sad for the way I treated her cause she payed for me to get highlights in my hair yesterday! I really wanna say sorry abd tomorrow (technically today) we were gonna have our girls day out! Please I'm MORE SAD THAN mad! HELP! (age: 12) SORRY FOR SUPER LONG STORY
