Would I be an Asshole

Would I be an asshole if I handed in my notice for my job, I work for a childcare facility ( daycare). I’m at my wits end I have been moved room to room inside and have done every single age group even though I have been there only 9months. I’m currently in a room where pre school is being thought, I work with two girls who are closely related and won’t talk to me at all only to tell be do something or to give out. They chat between them selves all day long, when I try to chat or involve myself in their convo they just ignore me. Recently I’ve found out one has covid and told every one on the floor we are on ( the building we are in has multi-pal floors) besides me on Friday evening, I only found out on Friday when the owner rang to see if I was okay to come in. I told my manager I want to move and that I’m not happy, that if I didn’t get moved by April or may I’d have to leave. She said the next moves are in June, I’m like what’s the point in staying as I’m miserable and it’s at the point it’s affecting my mental health. I have previously suffered with poor mental health in the past.
