>I feel as if I am not doing it out of any love for God, only fear of Hell and punishment.
Nothing too wrong about it. "Fear of the Lord is beginning of wisdom" after all. And "The sons of wisdom are the church of the just: and their generation, obedience and love."
>I live in Melbourne
Our condolences. But seriously OP, move. Imitate Lot.
>I feel angry that I'm so restricted in regards to sexual action,
Anger is passion. After Fall, passions are not longer under will and reason. But they can be. Of course they don't like it but if you overcome them, you will not be overcomed by them.
>I feel no love for anything but my family really
Detachment is virtue
> and otherwise life feels like passing time until the fearful judgement after death.
Read Ecclesiastes. And then four other books of Salomon.
> I praise God and pray, but there is no love or desire in there, only fear. Any words of wisdom?
First and foremost - move. Be it more conservative city (with latin masses) or just (mostly) catholic village.
Second, continune to pray and prise God.
Thirdly, read about "Dark night of the Soul". For it sound that you are in one right now. And from there, path to saintcy is very near.
