Am i in the wrong?

i cut off everyone this year and i really don’t care about being alone but i have one friend who i treat really well and my ways of caring is making sure she isn’t failing school but she doesn’t care and then goes to cry when all she did was play games and sleep and when she tried to go and do harder classes that required a 3.0 gpa i told her that she needed a 3.0 gpa and we have two weeks to raise it before we have to go test to be able to take harder classes and she says i’m putting her down? when she has f’s and d’s and i always help her to raise her grades at the last second but now she says she does that all on her own? she takes my work and submits it in and says she worked so hard and when i try to help her she’s saying i’m a bitch and goes crying to her boyfriend to talk shit i always tell her she’s doing well and help her understand any topics she’s misunderstanding but all she does is “well idc just give me the answers” am i in the wrong?
