i just don't like her and I know she doesn't like me
You are allowed not to like her very much atm op but presumably you still love her?
I am so tired of it all now that I just can't be bothered to talk to her anymore
As wearying as it is, and unrewarding, you cannot just check out. Get some support for yourself if you need it and think you might be depressed. I get that it is very, very hard. 
She is quite young, in my view, to be behaving this way. It does mean though that there is still time to turn this around What actions have you taken with the schools help to get her to arrive on time and hand in hwk?
I would be appalled that she is bullying others and throwing stones at people. If its remotely possible, my first step would be removing her from that group of friends, and putting her somewhere with higher expectations of behaviour. If that meant her moving schools then so be it. Peer pressure is so influential at this age , and she would be better off somewhere where that sort of behaviour is NOT cool. If she (and they) are like this now, what are they going to be doing in four years time? This needs to be nipped in the bud now.
To start with I would not be allowing her to hang around aimlessly in the park. Its very difficult during lockdown but I'd be making sure she was suddenly very busy. How does a 14 YR old sneak out? I'd be taking control of keys, lPhone, wi-fi, money etc. If she protests I'd be telling her that I loved her too much to be allowing her to let herself down like that and that I expected more of her. I'd be taking her volunteering (animal shelter?) and pulling in favours from extended family and friends to help to keep her busy.
Good luck op. I know its tough but her acting out now is a massive opportunity in a way to clamp down. Throwing stones is bad and could progress to something worse quite quickly. When the neighbours start getting involved its time to step up. Get some outside support for yourself too.
