Yr12 friendship breakup

I'm in year 12 and I fell out with my 2 closed friends and I admit it was my fault.
I'm going to refer to them as A and F. Sorry this might be a long story.
I moved to a new school in year 9 and that's when I became best friends with F and A. Then in year 12 our friend group had 6 people so 3 more people joined. F and I were really close.
Then one day my friend group and I were sat at the table we usually sit at except F was not there. L was talking about things that upset or annoyed her and I said one thing that annoyed me was when people sit and scroll on their phone while their in a conversation with you. Then L said F does this and it annoyed her. I agreed that I found it annoying when F did that and I said I've hinted to her in the past and she didn't understand. L then jokingly pointed out T was doing the same thing while we were talking. A then said to be the devil's advocate ( referring to F ) that sometimes people don't want to talk. Before leaving the table to go to lesson, I said I understood some people don't want to talk and that's okay so I have never confronted F about it as I thought it was a trivial thing to bring up and knew she didn't intend to be mean.
Then a few days later, on Friday, I went on trip so I wasn't at school but my friends were. A went and told F what we had said that day. Then later they were sat at the table and F kept saying at least I'm not on my phone. L realised someone had told and then messaged her apologising and said she didn't intend to hurt her. F was not happy that L and I had not told her directly. F then left all out groupchats. T told me what happened that evening. The following Monday, F ignored me and sat by the computers. That afternoon I messaged her apologising for decieting her trust and I really valued our friendship and I didn't intend to hurt her. She thanked me and apologised that she didn't intend to ignore us. In the end I said I understood and I would tell her directly next time so misunderstandings don't occur. She hearted my messages. But on tiktok she was reposting about fake friends which was annoying as she in the past had talked bad about everyone on the table. After my apology, she reposted a post saying she forgives but will never forget.
The next day F and A didn't sit at the table and don't talk to me. It's been like this since that incident. It's just 4 people on the table now. A unfollowed and blocked me on everything which was upsetting as A , in the past, has told me multiple time she disliked how F would sit on her phone and not talk to us. Now A is acting like she's never talked bad about F. ( ironically F has also talked bad about A in the past to me). A also unfollowed everyone else in the group except T as she didnt do anything and A has lessons with T. F hadn't unfollowed me on anything but kept reposting post on her tiktok about fake friends and how it's always the nice ones (referring to me). Then I unfollowed her on tiktok as it upset me seeing her reposts and in turn she unfollowed me on everything else.
Now we don't talk at school and in general and I've been feeling horrible for talking behind her back. I've lost two of my closest friends dues to my actions. I told my parents and my friends and they said to move on and focus on my studies as I'm unlikely to see them after six form but it feels so upsetting to lose friends you were really close to for over 3 years. I feel lonely and feel like I won't have such close friends again.

You've acknowledged your actions, but it sounds like everyone is in quite the muddle due to multiple people talking behind each others backs.Try not to let them get to you with the negative reposts. Losing close friends can be hard at first, but sometimes you just have to accept what has just happened. I know that's easier said than done. Do you have any friends who you're okay with to be with at sixth form in the meantime?

Thank you so much for taking the time to read my post and giving me advice. I'm trying to accept what has happened. Thankfully I have two friends L and T who I mentioned earlier but I don't feel as close.

No worries! It's okay if it takes some time to move on. Those friendships were special, but they weren't the only ones that you're capable of having- It might just look different next time. If you think your old friends were draining you more than supporting you, it's probably best to find better people. Be proud for acknowledging your mistakes in this situation, as not everyone can admit their mistakes. If you don't feel as close with L and T, try and take it slow. Hopefully with the more you socialise with them, you'll get closer overtime.

hi, I also have quite a big friend group (8 of us) and I can't lie there's usually some sort of issue/ disagreement every few months or so - usually they boil over, so I was just wondering how long ago this happened? That might determine what you want to do next. Either way, I'm sorry you're feeling like that, and don't feel too bad as you haven't been that mean, people say much more unpleasant things all the time

this may be a hot take but I think you’re better off and they’re being immature. yes it was a little shady but honestly I read it as you and T voicing an observation, saying it reads as rude, and moved on. that’s an opinion (although I agree!) but it’s not badmouthing unless you really sat there tearing into F and being nasty
A made a decent point but took it too far by running with something that was over and done with. you’ve done what you could, you apologised, and at this point it’s saying more about them than you. I commend you for respecting their choice and growing from it. if one mistake is enough to fall out over, I think it was bound to happen and you shouldn’t be so hard on yourself. let them leave you- it will all be ok
I’m 30 and you will continue to put your foot in your mouth haha, just far less often and in time, you’ll have the friends that will still love you and choose you even when you fall short
