I often wonder @Shaz51 - if there is a really accurate diagnosis for mental illness - it seems to me to be very complex and a name is just a name - yeah?
What he needs is a solution - and that would be great - and this is a very difficult situation.
There is so much I just don't understand about mental illness - and I have had reactive depression in the past - and I was lucky to have a good psychiatrist and no medication.
So - if it's not straight forward - and so hard to deal with - to live with -
