MsC Animal Behaviour personal statement help!

Hi everyone

I have decided to apply to do a MSc in Animal Behaviour at Manchester Met, the course starts in January.
I have a BA Hons Psychology (2:1) and according to entry requirements they do accept students with psychology degrees. I don't have any A-Levels in biology, I just have a C at GCSE.

So far in my personal statement I have written about the first time I studied animal behaviour in psychology, and how this interested me, and that I have done work experience at a vets and grown up with animals etc. I've also written about how I have taken up photography as a means of studying animal behaviour. I've written about how my undergraduate degree prepared me as I've studied research methods and statistics so I know how about lab work.

My main issue is that for the last three years I've been working as a support worker for adults with mental health. I know this doesn't have any relevance for an animal behaviour degree but I feel like there must be some transferable skills that I can write about. I just think otherwise it's going to sound like I've done nothing for the last 3 years.

The truth is that I have tried to ignore that I feel passionate about animals because my family didn't think I'd be able to pursue a career in it, so I haven't done a lot of actual work experience in the last few years.

I would really appreciate any help (sorry for the long story). I just really want to get on this course because it's the first time I've been excited about something in ages and I feel like I've finally realised what I want to do in life. I will be so disappointed if I get rejected!

Any help would be great, thank you
