Oh dear what
it sounds horrible. Great decision to come off social media.
We're going through a similar thing here. Dd had to block and distance herself from all her former friends back in May after they all started harassing her on social media the night before her first exam. She just stopped seeing them completely and has moved to a new sixth form, got her first girlfriend and is so much happier than she was.
Last night her former best friend had a party and invited everyone from their old school except dd and her girlfriend.
Definitely some homophobia going on in the wider circle. Even more complicated is that ex-best friend is bi and I suspect dd had a crush on her for a long time. Friend enjoyed the attention and is probably missing it now.
I thought dd had moved on and put it all behind her but last night raked it all up again. Who'd be a teenager!
