Those of us who have had to use the Military mental health system also need to step up and not be afraid to talk those who fear their careers will be impacted by showing the mental strength at a time of perceived weakness to come forward and put their hand up. You are all right in that it needs to be normalised while one is serving and not after one has left, and not stigmatised. I know plenty of people across the military who probably desperately need help that will never come forward.
I was lucky, I went back to flying and it didn't seem to impact my career, but the 'system' just fixes you to get you flying again ASAP, it doesn't truly fix you. That's for the charities to deal with when you leave....
Just my tuppence worth.
