Go/get

eslbroDifference between: I'm trying to get home. And I'm trying to go home.

None.

I agree that there is usually no difference intended. But here;s a possible nuance.

I'm trying to get home. Sounds a bit like my trip home has already started.

eg I'm trying to get home, but the roads are very icy.

And

I'm trying to go home. Sounds a bit like my trip has not started yet.

eg 'm trying to go home, but my boss keeps bringing me urgent

To my ear, the one with 'get' implies that the speaker anticipates that a little more effort is going to be required. There will be factors working against a successful trip home.
