Am I wrong?

My mom had showed me pictures of 2 MK shirts she wanted (Mother’s Day gift) & 3 pairs of shoes. I went to the mall yesterday, bought her 1 of the shirts, went around the store & bought myself 2 shirts that cost significantly less than her shirt & pants. I went into a shoe store & found some sperrys so I decided to buy them for me because literally you guys, I haven’t gone shopping in years & I only ever wear 2 pairs of shoes to school. I had other shoes but the sole was starting to come off & even my mom had said I looked like a bum so I threw them away. So I got the shoes & I saw some really cute casual sandals that I bought for her. They were only like $12. I left to the food court, bought her a plate of Chinese food & myself cause I was hungry then went back home. I feel bad because she might think I didn’t buy her what she wanted (besides the one shirt) because I bought myself things. But i don’t have a lot of clothes nor shoes in the first place whereas she has a big walk in closet filled with clothes & shoes. Last year I bought her a whole guess outfit with cute guess heels & I feel that I didn’t top that off this year.
