Imfab, I don't want to sound patronising, god forbid, but people will do whatever they want with your posts - you chose to make them on a public forum. There isn't some rule that we musn't comment.
And I think that was all it was 'comment'. I didn't perceive ANY poster trying to 'use your past against you' but simply making what I thought was a very uncontroversial point that you had expressed very extreme and distressing views about your past experiences; now, either that is something you have survived which will make you stronger and a better social worker because of it OR it is something that troubles you still and you had better deal with before taking on a very demanding professional role, which will make you confront those demons every single working day.
How is discussion along these lines 'using your past against you?
I think you have had some very helpful suggestions and I hope you do go on to investigate social work training - as I have said before, people are leaving the profession in droves and it is quite rare for me to see in court a British qualified social worker - loads from Poland and NZ, South Africa etc because LA have to go on recruitment drives abroad due to disastrous lack of home grown talent.
This causes HUGE problems, especially in London. I don't wish to generalise unfairly but on a number of occasions, clients of Afrcan origin have complained with some validity that the polish social workers have treated them in a racist way, possibly due to SW of recent Polish origin having much less experience and dealings with clients of African origin.
