Should I confront

So my mom and I don’t have the best relationship we act like we do but we don’t. In 10th grade she saw me sneaking with a guy she allowed me to go to he movies with. Of course I know I was dumb made her not trust me a little bit but I did it cause he told me he wasn’t going to see me unless he got sex I was stupid trying to please a boy I have learned my lesson we know longer talk. But tonight I found out I guess speculate that she has been telling my business to my family like personal things and why I’m in trouble. Stuff like that I don’t want them to know. Or how she found out I had sex a couple weeks ago. Yes I’m going to have sex we all do but I don’t want my family to know. So how can I trust that won’t get out. She has told them about my depression and all of her sisters came and talked to me every time they saw me and all my cousins knew and told me how I needed help and stuff. I don’t know what to do. I feel like she’ll take everything away from me even tho I’m 18 and say I can no longer hang out with ppl. What should I do ??
