Anger is an outward expression of depression.
I think you go through various stages during your dialysis career ...and that sometimes you hit a flat spot.
When it all seems too much effort. Things not going well.
And yes you miss the life you had.
God I miss the freedom.
Being able to travel.
Going down the pub and getting sozzled.
Being able to wear skimpy clothes.
You have that Why me moment...
And there are no easy answers.
But it is more common than you think.
Some say counselling helps. Or a good friend.
Or medication. (Wouldn't recommend prozac though)
Don't give up hope.
Find a way through.
