What Should I do?? ........?

K, I have these pants which are my absolute favorite! (: But lately i've gotten a little pudgy ): & It was hard to fit into my jeans. I decided to try to eliminate all the room i needed. So I used everything I could think of, surround wrap-which worked but hurt ): & my mother's corset. :/ I know...weird. But these r my fav. jeans! I did what i had to, & i didn't feel any shame or disgust to it until i yawned...haha don't worry there's more to it. Anyways, my shirt got lifted up & she saw it...She didn't say anything but i think she just turned the other direction.I'm thinking it's because dad was there, but idk. I feel sooo embarrassed now! What should i do?
