Back at home and feeling down..?

i moved back home when i ssplit with my partner and left my modelling job. now i am frantically searching for work and a place to live, but my mum is being nasty. she is constantly undermining my looks, pointing out my flaws, leaving me fattening snacks around, influencing my dad and sisters against me. also she has gone on a frantic diet and starving herself, i think she is worried as she was very attractive wen young..she is buying all this y clothing, stealing mine, yet saying how she wants me out of the house a.s,a.p..even my brother is annoyed at her. why does she hate me?
