Jonathan Martin, the retired football player who left the Miami Dolphins in 2013 after accusing teammates of bullying, said Wednesday that he had attempted suicide “on multiple occasions” because of long-simmering identity struggles and the stresses of the N.F.L.
In a lengthy post on his Facebook page that was shared to Twitter on Wednesday, the former offensive lineman detailed the mental difficulties that he hoped his on-field accomplishments would help ease. They did not, and the locker room was one of many environments in which he said he felt like an outsider.
