Hi Gilliann,
Do you have a supportive GP? It might be worth asking them about the possibility of a "Mental Health Care Plan" which can give you up to 10 sessions per calendar year of Medicare subsidised sessions with a psychologist on the basis of issues like anxiety, depression, adjustment difficulties etc. It might be worth considering. In your situation there might be some psychologists out there who may consider "bulk billing" you so that you do not have to pay a gap. The Cancer Council may be able to put you in touch with psychologists who are experienced in this area. Also check out the APS (Australian Psychological Society) website www.psychology.org.au. There is a "Find a Psychologist" database which could be useful to find someone in your area with specific expertise.
I have had some sessions with a clinical psychologist since my diagnosis and this has really helped me get through so far.
Take care
Karen
