I am trying to see this from the perspective of your mother ...
You have just spent two years becoming a Jedi ... and now you suddenly declare that you are a Muslim.
Of course she must think this is just another phase, another teenage patch her son is going through ...
(To be honest, that's what
I would be thinking if I was in your mum's shoes ...)
I think as a mother she will be looking for signs of whether you are serious or whether this is just another phase.
Try to think back,
how convinced and serious were you about becoming a Jedi?
Is you interest in Islam the same? Or is it different?
Will you be looking for something else in two years time?
(You may only be able to answer these questions in a little while, with the benefit of hindsight, but I think these are serious questions for you to consider)
I guess your mum thinks that only time will tell how serious you are ... and she is probably right!
Given that you seem to know very little about Islam at this stage yourself, I suggest that you give yourself and your parents some time.
Be patient!
Love and respect them!
And let God work in all your lives!
Peace
