After a while she had to five up trying to think.

What he himself must feel, I could only try not to think of.

But I try not to think about these things at all.

She tried to think back into those years, to remember.

So I went through my mind trying to think of a place they might have gone.

He tried to think of something else to say but nothing came.

She probably tried not to think of him at all.

She tried to think of the moment in which he had made up his mind.

Finally she gave up trying to think of what to do.

I'm trying to think of a story I should tell.
