My (19F) Mum (54F) actively discourage my writing and tells me I should be focused on encouraging my sister (15F) to write instead.

I have been writing novels ever since I received a cheap laptop for Christmas when I was 11. I love writing and everyone who reads my stories enjoys them. So far I have written one particular story, around 5 times (90,000 words each time). Every time I finished I would end up starting from the beginning as my writing would improve so much, I would be cringing as I began proof reading from the start. Aside from that story, I?ve been writing about 3 other novels on the side and entered three writing competitions and won first place with two of them.
The latest writing competition (I was 18 when I won) I was congratulated personally by the head judge who encouraged me to start publishing my stories. I remember him telling me I had something special and I could definitely make a career out of this. I cried when I got home as I?d never received this kind of encouragement from my family...
My sister, on the other hand, has never written a book. When she was around 7, she would hand write stories in a note book which my parents would enjoy reading. They showed one of the stories to her teacher and her teacher found it cute. As she grew up, she lost interest in writing and hasn?t written anything since. Yet my parents are still so focused on the stories she wrote when she was little, and are convinced she will become the next best selling author.
Recently I started publishing my work on amazon. I?ve only published one book so far but it?s doing really really well. I?ve just finished the second and it?s due to go live today. At the moment I am studying at university and it looks like I?ll soon be able to quit my part time job as writing will earn me more. I told my parents how well it?s doing but they seem very disinterested. They told me that I should be giving advice to my sister and encouraging her to write.
Last time I visited my parents house, my dad asked me how my book is doing, I had just begun to explain about how many people had read it before my mum cut me off and asked my sister if she was writing anything.
My sister texted me this morning showing me some screenshots from my mum. It went something like this:
Mum: why aren?t you publishing your stories online
Sister: I don?t write stories
Mum: you should! If your sister is making some money then you certainly can.
Seeing that message really hurt my feelings. After all these years my mum is still convinced that my sister is a better writer than myself. My sister hasn?t written anything since she was 8 but my parents are still convinced she?ll be an author as her English teacher once commented that her creative writing is very good.
I hate this so much. I wish they would just be proud of me for what I?m doing. Instead they?re telling me to encourage my sister to write, despite her having no interest in becoming an author.
TLDR: Despite me being a published author and winning writing competitions, my parents do not care and are convinced that my disinterested sister is a better writer than me.
