I dont think has was seeking attention or that he was too hard on himself. To me he always looked like somebody with some level of mental issues.
Blaming himself after every goal in every kind of circumstances, even after wins was very very concerning and as was a major red flag. You could always felt that instable vibe around him even when things were going pretty good for him, and suddenly he collapsed again, some say because of the injuries, somes say because of the contract talks, all in all I do think he is not there mentally to handle this job, which is sad and I feel for the guy because I always liked him.
Other than asking 5M for 5 years which we couldnt afford I think this was a huge factor we let him go. This was always the case throughout his entire career no matter which team he played for.
