@Explorer7Sorry, I was getting lazy with my typing... MHCP is mental health care plan which my GP suggested as it gives me 10 subsidised psychology visits a year.

I've continues to look at other things to add to the list of things to get involved with but having had quite a few setbacks in recent attempts my confidence and motivation has taken a big hit and i'm sort of taking a time out to rethink what I want to do going forward.  It seems a lot of people lose interest in even having me as a volunteer when they learn i'm undergoing permanent cancer treatment, even if it is just injections and tablets at the moment. 

Add to that recent issues with the psychologists I've been seeing (which probably deserves a separate lengthy post to go into) that has me uncomfortable in continuing and i'm feeling a quite a bit lost as to what to try next.

In a way the health side of things is easier to deal with... I just do what the doctors and nurses tell me to.  As you said, while working the structure of your time can be largely dictated by others.  When you're trying to fill you own masses of free time, it then falls fully on ourselves, as well as the confidence and motivation to continue.
