The England batsman flew home from the disastrous Ashes tour this winter complaining of "burnout" and returned to action for Warwickshire earlier this month.
However, he has since announced that he is taking another break from the game, and Warner feels that it is a smart decision for the 32-year-old to prioritise his health.
Warner was criticised for branding Trott as "weak" in the days prior to his departure from Australia in November, and has admitted that, in hindsight, his comments were probably unnecessary.
He told reporters "My comments at that time were probably over the top. When I didn't know there was a problem with Trott, I said what I said, but that's in the past now and we've moved on from that.
"It's always disappointing to hear something like that about anyone. It doesn't matter who they are or what job it is. If you feel like you can't give 100 per cent and commit 100 per cent then he's done the right thing. What happened to him last year and what he said in his recent interview shows he's got problems.
"I wish him all the best and I hope he can get through this and get back on the park. If not, I wish him the best for his future endeavours. If he gets the opportunity to play again and represent England on the park it'll be a good tussle again."
Warner is currently part of the Australia 'A' squad that is touring India.
