Ugh help.

Not sex related but i just started my new job, i work in a group home with disabled/mentally challenged people and today i just found out that BOTH of my ex best friends that did some really crappy things to me & behind my back work there, and one of them actually is assigned to the house i’ll be working at. I lived with them, they were my sisters, & turned out they were sleeping with every guy i talked to, even my at the time boyfriends, they were always talking about me to other people behind my back & i was so excited for this job. We also have the EXACT same schedule (you can see your co workers schedules & contact info) now i don’t even want to go to work & since she’s been working there longer then i have i figured i’d text her & ask her how the clients were and what the house was like, she just acted bitchy and like she knew everything “have you even done work like this before” “don’t affect my work i’ve been there you haven’t” like.. what??? mind you i’ve done this work before, but i guess since she’s been there longer she’s all high and mighty.
