Failed dissertation

As the title says I failed my dissertation, which due to having accepted a job in London and having no time I was unable to redo so eventually took the decision to take my degree as it was (I was doing speech therapy where you take more modules) this has meant however that although I have my degree in speech therapy I don't have the licence to practice as a therapist. I had had a rough final year with the death of a close family member and the breakdown of a long term relationship which massively impacted on my studies and I felt majorly disheartened once finding out about my dissertation. It has taken a year since all this happened for me to finally realise that I made a rash decision and I do really want to be a therapist. I'm not sure what to do next, I know that all I need is to redo my dissertation module for this to happen but as I have already taken my degree as it was I'm unsure as to whether this is even possible, I don't really want to contact my old lecturers as I felt they didn't really support me, but was wondering whether another uni that does this degree would have any options for me. I don't want the three years to have been for nothing as currently my degree might as well be worthless. […]
