Hi Sugarmag
Not sure i can be much help but thought would add some words of encouragement. Childline is great experience - their training and support is very well regarded. I was a volunteer for about 18 months and learn't loads in that time, although this was a while a go (am now a clinical psychologist).
The only thing i have to add is that you might find it a bit tougher to get a job specifically with kids - although it depends on the age. Most 'input' with younger children is systemic - that is, working with parents and carers etc and therefore isn't within the traditional counselling model. I work in a child and adolescent mental health service, and we have one part time counsellor within a huge team of other roles (nurses, social workers, psychiatrists etc.) That said, there is growing demand for cognitive behavioural therapy for young people, to which your backgroud may well be suited (if you are interested in this, try the BABCP.com website. There are certianly non nhs employers who do employ counsellors within child services, but often with teenagers and young adults (eg after care services, post 16 education services etc.) Most counsellors who work from GP and mental health services work with adults (although there are exceptions to this.) and there are generally only limited numbers of NHS counselling jobs with children advertised. If you want to work in a therapeutic role with younger children, then it might be worth considering if counselling is the best training route for you, or whether another role would give you more scope and opportunities.
Sorry, that bit wasn't so encouraging was it. I think its just worth clarifying your goals before you get any further and making sure that any course you complete prepares you for a specific role at the end of it (i know people who have completed a psychology degree only to be suprised at the end of it when they can't get a job as a 'psychologist'. )
That all said, if you really enjoy childline it may be worth talking to your supervisor about the possibility of future work with them. They do (or at least did!) employ fulltime staff.
Am not suprised at your response to BPS
, but might be worth a quick look at the site as their training stuff is usually pretty useful. There is also the British Association for Counselling and Psychotherapy website (BACP.co.uk)
Hope that makes sense, and good luck
