I have a problem. It's not l’amour it's my Friends

I have two best friends. well kind off. i have been really good Friends with one of them for 4 years now. we are like sisters. my seconde friend is a little problematic and she has been going on my nerves and insulting me but i never told her how agressive her behaviour really is.

so i have been chatting with her (friend 2) and she got mad on me and told me that she will stop hangign out with me. when i got to school the other jour i told her i got hacked. but i didn't. the suivant jour i had toothaches and i went home. i don't know what happend later that day,but my friend(1) called me and asked me about it and she told me i'm a liar. and today she was rude to me. she told everything to the seconde friend and now they won't talk to me. i don't understand what did i do that was so wrong to the first friend that now she won't talk to me? all these years i have been helping her with EVERYTHING. now she turned her back just like that. i feel like they got together against me. They are being rude to me and criticizing my every move! especially friend(2).

please help!
