I know this is a hard situation. I have just needed to cancel my next 3 sessions as I can't afford them. I started seeing T thinking 6 sessions and I would be cured, nearly 2 years down the line I too add up all that cash and think what I could have spent it on. T had said we could negotiate a reduction, but I do think how much could T reduce it by and it would need to be 50% to have any impact and that would be embarrassing to ask for.
However on the other hand money is money and even a small amount each week, builds up to a larger sum over time.
I think you have explained things really well in your post - T I didn't think I was in for the long haul and thought for a limited time I could meet the cost of the sessions. But now I realise that there is more work to do than I thought, I am now struggling to meet your fees. I would appreciate a reduction in fees as you had previously indicated, so that I can continue to commit to the sessions with you for a longer period of time.
It is so much easier doing this for someone else
