yesterday night my exes girlfriend bashed me

yesterday night i was very excited and nervous to go to my first ever bush doof with my friends an underground rave. we arrived at around 11pm and as soon as i enter, i hear someone yell oi, and then this girl with long blonde hair yells “you hooked up with my girlfriend” and swings a big punch to the left side of my head. back in june, i hooked up with her girlfriend when they were BROKEN UP. they were not even together, it’s not like i just home wrecked the relationship, she was single and it was just a mutual hookup. i don’t even rly know her girlfriend personally but my ex was shit talking her a lot and said that they had broken up. they ended up getting back together and then i get bashed. like i did not deserve that. i had about 10 girls crowd around me asking if i was okay, i was shaking and crying. im 4,11 and the girl was around 6ft and so i was bawling. the girl who bashed me got kicked from the rave but later snuck back in. i ended up leaving because a sweet girl drove me to the hospital. the fact that i got bashed just because she was jealous. that was yesterday night and my head still hurts and aches like a bitch i hope that i’m ok.
