Does my mum love me at all?

when I was two my mum left to come to england(my parents were still together).four years ago my sister me and my dad came to join her.six months ago my dad broke his leg,was diagnosed with hepatitis b because of a dodgy vaccination and my parents had a huge fight.they're still together but my mum is now always angry.she insults me and yells all the time.she says I'm a laZy child and she might aswell rare goats. I feel worthless and degraded.sometimes I feel liike just running away from all of it.she loves my sister.she buys her loads of clothes and she never yells at her.I don't neccesairly need an answer just some comfort.I'm 12
