I'm a bit embarrassed by this but struggling to know what is appropriate. I have never had a job. I was a high achiever during my younger years and started uni but my life has been a mess. I had mental health problems and ended up dropping out of uni and having my first child at nineteen. I was a single parent on benefits for a while. Obviously, I'm not going to say all of that, but it means that there is a whole lot of nothing on my CV for many years. This doesn't make me an attractive prospect.
I have the qualifications they ask for in this specific job listing, but so will many other candidates. I have some relevant (voluntary) experience to put on my cv, but I don't know how to make myself stand out. I am intelligent and pick things up quickly, but am particularly good with numbers. I am very suited to the role but it's hard for me to prove this without experience. I was awarded something during my younger years (not by my school, it was a national thing) which is sort of relevant to the the job I'm applying for now and will go some way to showing that I am actually good at this... but I'm now in my early thirties.
I can't tell whether this would be a way of making my application stand out when I don't have much to work with, or whether I will be embarrassing myself by sounding like I'm trying to 'show off' about something which happened a long time ago and is no longer relevant, especially as the job itself isn't very academic.
My husband lost his job just before lockdown and things are getting a bit desperate. What would be best?
