I feel disgusting for past actions I don't know how to get over it

I've always been shy and awkward around boys. I was kind of rewarded for being innocent because of it by my mom and people at my church. They saw me as a "good girl" and complimented my mother for her parenting because I was homeschooled. Well I had a phase when I was 14 that lasted a full 5 months.. I got drunk twice and sent inappropriate pictures to multiple older men. I wasn't manipulated into it I sent the pictures willingly. When my mother saw I was posting on TikTok (which I wasn't supposed to be doing) she decided to search my phone and found my Instagram messages with a 19-year old. She made the most disgusted face and I felt so bad, I started screaming and crying kind of like I was throwing a fit. Even to myself this seems like something I'd never do, but I did it. I question my character now and I feel used up or something. It doesn't help that I was pretty mean and bratty from 10-13 so now I feel like I've always been a bad person. My mom has brought it up multiple times and I feel so gross now (I feel like this is going to attract weirdos so I'll turn my messages off)
