An MP has said he plans to take time out from his official duties to deal with “mental health and personal issues”.
Jared O’Mara was accused of treating his constituents with “inexcusable contempt” by his former press chief.
Mr O’Mara was criticised in a flurry of tweets posted from Mr O’Mara’s own account by Gareth Arnold on Tuesday.
The Sheffield Hallam MP apologised to “friends, family and constituents” and said he was seeking treatment.
The 37-year-old said he would issue another statement in due course.
“I want to become a better person again; like I was. I feel I’ve become unrecognisable and I want to make amends,” Mr O’Mara said.
“I need treatment for my mental health and rest first though.”
Mr O’Mara was also critical of his treatment by Jeremy Corbyn’s office and claimed there was a lack of support from the national Labour party.
In response, a Labour Party spokesperson said: “We take the welfare of our MPs very seriously and, while Jared is no longer a Labour MP, we are concerned for his welfare and we have continued to provide support to him, and will continue to do so.”
In one of a series of highly critical comments posted on Mr O’Mara’s Twitter account, Mr Arnold said: “Sheffield Hallam deserves so much better than you.
“You have wasted opportunities which people dare not to even dream of.”
Mr O’Mara was elected as the Labour MP for the constituency in May 2017, ousting former deputy PM Nick Clegg.
But he now sits as an independent MP after quitting Labour 2018 after he was suspended over alleged misogynistic and homophobic comments posted online.
