My friends ignoring me

So bacially, I fell out with a friend 2 months ago over a silly little argument and then we became bestfriends again although she has been blanking me but FaceTiming and texting all the people in our school group (wasn’t just me who fell out with her) it was other people but she is fine with them!! It makes me super upset the other day we was all invited too a party and then 4 all got dressed together but I was the only one who never got invited ! Let alone I have people bullying me outside of school we’re my mum has had to ring the police! Do that’s all I need. Would you say it’s bullying??
