Please give me suggestions

I'm in highschool starting a new year after moving back to my home town. After a while I enrolled and found out I'm in the same class with my old classmates and friends, they all changed (maybe?) A lot, but they are still kind and have their features that stand out, apparently 3 of my friends made a friend group, one male (M) 2 girls (G1 and G2) I don't wanna point out any names. So M like G2 and confessed but she wasn't ready, she declined(?) And they became awkward and had a fall out with each other. All 3 ended up in the same class with me and they were all close friends of mine, G2 started having feelings for M and sho told me, I supported them completely and I was so excited I told one of my friends about it. What I didn't know was the entire fall out and confession incident, so I accidentally blurted out G2 x M as a ship name to my friend and M maybe heard, I didn't hear much but before I said it to my friend he was venting to a group of classmates that approached him, he was crying and I went to ask G2 and that's when I learned about the incident. I want to talk with them and just stay in between but I think I've gone in too deep, my stomach hurts and I feel mentally drained and stressed due to school work since it's a religious school and a strict one at that, they accepted me even tho I'm of a different religion. I need help and I need to get this off my mind, I apologized to M through a message since I only realized once I got back from school, I plan to formally apologize face-to-face. I'm a bit of an over thinker, It'd be appreciated if you could give me any suggestions as to what I can do about this subject. Thank you for reading my rant and I will accept any critism even if it's practically hate as it can be used as a suggestion per what I asked. I thank you again and have a good day/night and stay safe to everyone. You are enough and deserve every good thing you have, if you don't have any good things you deserve to receive it all, mental things or physical.
