How do I cope?

I just wanted to point out I placed this as anon. I didn't know which topic to put this as. I didn't want to put this into Controversy Corner because I knew people would comment saying its against the guidelines to be anon or some pish posh like that. ANYWAY. I'm needing advice. However this may not be easy since everyone has a way of dealing with things differently. So let's get into it.. at the end of middle school early high school I was a bit of a wild child. I look back on things and I wonder "wtf why'd I do that?" then I'd feel guilty, then forget about it for the time being. Well.. my mom and I were talking and out of nowhere she's like "I remember when you said this because your friend tattle tailed, by the way I took 30 screenshots." First off its in the past, second that person isn't in my life anymore so who tf cares, third just blows me away because why would she screenshot and make me feel guilty. I'm sure there's a number of people who've done far worse than I have. Not that I'm judging anyone. You do you boo, I'm just trying to prove a point. Since I've rambled a ton, I feel like my mom is constantly slut shaming me, even though I'm still a virgin. She's like "when I read these texts I think of you as a whore." Also, this happened around 5 or 6 years ago. My mom is a very negative person and always has been. If I could ever think of a happy thought I'd end up silent because there never was a time where we got along. I know this is so long but please, anyone, give me your thoughts.
