need advice please its urgent
so basically i have a friend who i have been friends w for over 8 yrs from school and now at present she started priortising other friends over me and js stopped opening up to me but when she did hung out w me shes her usual shelf and makes plans but does the same plans w her school friends at our allocated time and we are basically a trio but its like they js support each other no matter what if she is wrong the other friend would back her up no matter what and it js feels like they both have a spl bond which i dont have w eitheir of them and when i confronted her abt keeping secretes from me she brought up something i did to her 3 months ago she holded a grudge even tho i said sorry during that time she lashed out on me and said she hates me and told me this is why i dont have friends that time i had a tough life at my school and i opened up to her but she used it against me whenevr i hang out w them i feel so left out and yeah w have fights usually now and i have js come to realise that in7 yrs of friendship i was never the friend she had a bond w we switched like several friend groups and it js feels like she had a bsf in that group and js treated me like an option and its js exhausting but i dont want to make nay drama about leaving im justt exhausted especially w my parents too they js yell at me all day long i am js exhausted and its kinda fucked up that i look forward to sleeping all day.
so should i js cut everything or am i js the problem
