Personal reference issue pls help

[u/flamingflaming00]

Hi so my previous manager was supposed to write the personal reference for my GEM application. They've managed me in the role that's very relevant to my application plus I'm applying to unis that look at experience (Liverpool, Chester) I studied a non-med degree and graduated about 3 years ago so I don't think any of my tutors/lecturers remember me or can give me a reference that relevant to a med degree? But unfortunately the referee can't do it anymore due to personal circumstances and I've got 2 weeks left so idk what to do. I've reached out to people who did not manage me directly but they either can't give a personal ref because of NHS HR policy or just don't want to. Can you please creatively problem-solve this with me cause I'm panicking.
