I lost everything today.im so heart broken.tell me what should i do?

my huby & me live in different countries bcoz of the imigration process.well my sis in law hates me coz she thinks that other family members loves me more (which isnt true).now she doesnt talk to me but is very sweet with my hubby.i had good relations with his husband too and we were like friends and siblings but then he misbehaved with me coz he thought i was saying somethin against his wife when i was not at all talkin about her.i was just advicing him not to share everything with other family member and i told him his wife shouldnt do that too.well all i was trying to do was to protect them.i cried when he misbehaved and now we are not on good terms.i have always been there for him like a sis.my hubby loves his bro( my bro in law) a lot and is always protecting him.no matter wat he do.today when i was talkin 2my huby he came and was upset coz my huby didnt reply to his wife msgs.i got upset and as a result my huby shouted at his bro and they had a v big fight.my huby later on shout
