I thought it was a really honest, open piece about how James experiences depression and ADD. It will show other sufferers that these conditions can happen to everyone, regardless of their circumstances. He was very brave to be so refreshingly honest and I do think it will help other people.
The cynical side of me read it thinking about how different his experience is compared to other people. CBT on the NHS, for example, is often limited to 6 sessions. Medication is usually always offered before more expensive forms of therapy which treat the root cause. People from less privileged backgrounds aren't able to take time away from work to recover without this being a huge financial burden on their families, nor do people with ADD typically have the means to set up their own businesses because this suits their working style better.
That said this is no reflection on his particular article. James would never have been able to capture the experience of people who are more disadvantaged and he does acknowledge how privileged his is. I hope he continues at a smooth pace with recovery.
