I'm the opposite actually. I told my parents what I wanted to do but my Dad knew better. I wanted to do Art and Drama GCSEs but was told I wouldn't get a job with those. He picked my subjects and I was forced to do Geography and a subject I can't even recall (I got 9 GCSEs but can only remember 6 of them and have no clue what the grades were back in the 80s). He then abandoned the family for a woman 2 years older than my brother and left us all to our own fates, no doubt patting himself on the back for installing our great educational foundations.
Advice is only as good as the mentor, in your case your Mother. I too find it odd that you blame the person least equipped to support you and not your father who had the knowledge you sought but chose to withhold it from you. However, like my father, he may have mentored you to be a facsimile of himself which wouldn't have been right as you are not him.
You are the expert on you. You know what you enjoy doing and what you are good at (there's usually a correlation between the two). There's lots of careers advice online, Barclays Life Skills may be aimed at a younger audience but is a good place to start and the government's National Careers Service could help you explore career options.
It's time to take ownership and agency for your own life and start planning forward. When your daughter hits 13, listen to her, support her in what she's good at and what she enjoys. The Kabil Gibran poem, On Children, sums this up beautifully...
Your children are not your children.
They are the sons and daughters of Life's longing for itself.
They come through you but not from you,
And though they are with you yet they belong not to you.
You may give them your love but not your thoughts,
For they have their own thoughts.
You may house their bodies but not their souls,
For their souls dwell in the house of tomorrow,
Which you cannot visit, not even in your dreams.
You may strive to be like them,
But seek not to make them like you.
For life goes not backward nor tarries with yesterday.
