Any problem relating to low self esteem or difficulties in childhood, that is.
I wish people would acknowledge that firstly counselling is out of reach of most people due to the cost. I know it is available on the NHS in some areas, but this tends to be for limited periods (it's 6 sessions here) and there's a long waiting list.
Plus, although depression and anxiety are medical issues some problems are not. Having a difficult childhood isn't, having slightly low self esteem isn't, and so on.
It's not always easy to get to if you have young children and/or don't drive.
Also, is it effective for everybody? I'm concerned as I feel counselling is, to be blunt, the new cure-all, but I don't think it's helpful for everybody but every problem on here at the moment - 'get counselling!'
I have had counselling which I didn't feel was enormously helpful, but this isn't saying it is never helpful - it's saying its a possibility amongst other possibilities.
