Pursuing psychology or mental health nursing

I am certain I want to be a clinical psychologist or therapist, I'm preparing to apply to unis and am unsure whether to pick psychology or mental health nursing. I want to be able to work after uni to fund my post-grad education, mental health nursing will allow me to gain significant experience whilst doing so. I don't mind doing a conversion course in psychology. My one con is dropping my dream of studying psychology but I'm so worried I won't be able to find relevant work experience after my bachelor's due to the competitiveness of the course. There is a huge risk due to the no man's land in psychology between the BSC and MSc! Can someone advise me which route would be best, I just want to be prepared for the Dclinpsy whilst also having an earning potential and steady life to fund my further education! Help would be much appreciated 💗
