I feel I have to comment on this topic. In the latter part of my service career my mental health suffered due to operational experiences and I toughed it out for more than a few years, deterred from seeking help by the 'zip up your man suit' attitude of both my colleagues and my superiors. Huge mistake for me and my family, I should have sought help earlier it may have limited the damage. However, once I stuck my head above the parapet I was treated as a pariah by so called friends and chain of command alike, any sniff of a career was gone in an instant and I was hammered in annual assessments. I got help through several DCMHs but sadly I could not be fixed to a standard required for further service.
All I am trying to say is that in my experience the RAF has a very long way to go to actually deliver on the promise that it cares for its people and that the stigma associated with mental health problems is looming as large as it ever has. I was in a trade that trumpets its care for its members; don't make me laugh, their efforts were risible and mean absolutely nothing. From Med board to discharge was 12 months and I heard nothing from my chain of command throughout that period........ I even wrote to the then CG (gives you a clue as to my trade) explaining my experience; it took him three months to reply and even then the letter started "following your decision to leave the RAF".
This was not many moons ago, I left in 2015 and actually it was for the best but the treatment meted out by my chain of command has left a very bad taste in my mouth and the only help I have had is from a charity who have been brilliant. NB it was not my Service (Regiment) charity.
Finally I would give advice to anyone suffering to seek help early and reap the benefits to you personally of that help but beware that it will, or is very likely to limit or curtail your career in the present climate of all 'talk and no action' within the Service.
