Hi Alstare and welcome,
I'm sure you realise most of are going to tell you to keep away from those suicide forums if you possibly can, although if you browse around the forum you'll see many of us have planned how and where, I certainly have but the thing that stops me is knowing how badly it will affect my friends and family (I lost a close work colleague from suicide and it affected me dreadfully).
It can be frustrating while the medics get things sorted out and I know how desperate I have felt when nothing seemed to be helping me.
Two things cross my mind, one is wondering if there are any support groups for ex service personnel and the other is to say that if you are dismissed for a genuine illness its possible to take your employer to court for unfair dismissal if you have worked there for over a certain length of time. I'm surprised your doctor hasnt signed you off sick, if not could you tell him/her how you feel and ask for a sick note? I know how difficult it is dealing with things like that, at my worst I shake and feel sick when I have to see the doc, thats if my panic attacks and agorophobia dont prevent me actually getting there.
Everyone here will help as much as they are able, talking about this horrible illness can also help a lot too
