This will depend on the circumstances of your course. Are you doing the High Intensity Course as part of an IAPT service where it is both a PGDip qualification as well as a job?
In those situations the two parts are intertwined, but it may be helpful to see if you can separate them. Even though you may lose the employment part, it may be able try completing the BABCP training part independently when you are in a better situation. That may be that you pay for the academic component (or part of it) for the rest of your credits, but also complete your clinical cases in a voluntary placement within a trauma service. Maybe your current service may even consider it, but there are several charities that will get you trauma work and may even provide supervision. The BABCP may be able to give you more objective guidance than your employer or training course.
I appreciate that may be a bit messier and also costly in a way that funded integrated training isn't, but it's a small hit for a recognised qualification that allows you to access the workforce. If things have been tough, you may even want to take a break for a bit and do something non clinical for your own mental health, as presumably your credits will stay and you will still have accrued your case log.
