What do I do

My ex best friend manipulated one of my close friends into believing her side of a fight she started over a 3D printed spider that I gave to my friend and my ex best friend wanted it so badly she tried to jump her and when I took my friends side she got mad and manipulated all my online friends into hating me while I was grounded I wanna cry because no one will believe me and now I really don’t know what to do I’m 14 and both of my friends that were fighting are 15 were all freshmen so I don’t know why my ex best friend would pull elementary bs I just want my friends back.

I'm a little lost as to what made them all turn against you so quickly but it sounds like they're just bad friends, especially if they're willing to drop you so easily?

I got grounded for 3 weeks when the fight happened and that was enough time for my ex best friend to convince evreyone I was In the wrong I still don’t know how though considering I wasent even in the fight.

Human will always be human. Just ensure you are doing the right thing and you not really the one at fault. If you are not be sure if they are reasonable people, they are coming back.
