If you are funding your sessions yourself, the number of sessions you have is entirely up to you. As this is a private practice, I can provide counselling and psychotherapy on a short, medium or long term basis, depending on what is appropriate for your individual needs, there is no set number of sessions.
However, if your sessions are funded by either private medical insurance or an employee assistance scheme, then the number of sessions you can have will be determined by the type of plan you have. Plans vary widely, so to find this out you will need to contact your provider in the first instance. More information on accessing therapy via private medical insurance can be found here.
