Here are a few useful links and some of my favourite websites:
The BACP is another professional body of counsellors and psychotherapists.
They have a great section in their site called What To Expect…. Well worth a read!
More information about TA (Transactional Analysis) can be found here, on the ITA Website
Crisis help for those needing immediate support - the Samaritans provide someone to talk to, 24/7.
For general medical issues of concern, including mental health, try NHS Direct or your local GP.
