The 32-year-old has not played for England since last year's Champions Trophy in Pakistan, where he scored only 33 runs and took three wickets in three matches.
Livingstone, who has played 60 T20 Internationals, 39 ODIs and one Test for England, described that tour as the "worst experience" of his career and said communication from team management broke down after he was dropped.
Coach Brendon McCullum broke the news to Livingstone that he was being dropped last May in a telephone call lasting barely a minute, he told ESPNCricinfo.
"I asked why; they said they wanted to try someone else. That was off Baz (McCullum). Brooky (Harry Brook) sent me a text.
"Keysy (director of cricket Rob Key) said nothing, said I'll speak to you in the summer. I actually rang him one day and he said he was busy at a Test camp at Loughborough, and then I didn't hear from him until the end of September.
"That probably sums that group up as a collective. That was a bit of an eye-opening experience about the group and the regime: if you're in, you're in, and if you're not in, no one cares about you.
"I was asking for help and pretty much all I got was that I care too much and I need to chill out a little bit."
As well as his international career with England, Livingstone proved popular with Australian fans when he played with the Perth Scorchers in the BBL from 2019-21. He was then picked up the Melbourne Renegades, but withdrew from the 2022 season because of international commitments.
The England and Wales Cricket Board did not immediately respond to a request for comment made outside UK business hours.
