Translation help: 私が困っているのがはつおんですね


This is a trascript from a podcast I was listening to. The woman was asked
about what she thought was the hardest aspect in learning english, to which
she replied

> 私が困っているのがはつおんですね

So... why 私が instead of 私に (meaning 'to me'). Not only that but, what is the
role in the sentence of 困っているの? It is the continuing action conjugation of 困る
(to worry) but how does it fit in the sentence? And what is the role of の?

Thank you very much.




私が困っているのが is translated " what I am troubled with is" and this "の" is used in
a nominalization of a sentence and verbs and so on. For example,
"私が勉強しているのは、大学に行くためです"、"走るのが嫌いです"、"悲しいのが嫌です". And 私が困る of this sentence is
that わたし is subject and 困る is predicate, so が is used because に isn't set
behind a subject.

In addition, if you want to use "に", you say 私は、発音に困っています and it's translated
I am troubled with pronunciation.
