Thank you Emu noodles. Myself I'm from Jo'burg, but currently in the UK for 3 months. So I will be back in early January.
It seems that the best places to get support in Jo'burg are the guys at the South African Depression and Anxiety Group (SADAG) and The Anxiety and Trauma Clinic, both in Sandton.
I plan to get involved with both groups when I'm back.
