I'm working on a paper about dealing with anxiety over long-term degenerative illnesses.
The philosophy being that all of life is uncertain, and that the perceived need for certainty should be challenged as unhelpful and unnecessary (we all know worrying doesn't change circumstances!).
So for example, someone having chemotherapy for cancer doesn't know if the outcome will be that they live or die, or someone with multiple sclerosis doesn't know if they will end up blind or in a wheelchair. Worrying won't change anything except the journey leading up to the catastrophic event if it actually happens.
Part of the discussion involves self examination and asking from others: how do you deal with uncertainty in your own life? Do such thoughts/worries only enter your head when you are inflicted with problems in life, like financial ruin or illness, or is it niggling in the background all the time?
