I'm really starting to stress out about this 
Background: I'm in my early 20s and I graduated from uni in the summer of 2015. I didn't find a "graduate job" straight away, instead I moved back in with my parents because there was a job going at my local shop (small convenience store), I'd worked there before as a school pupil/student and was only intending it to be temporary (admittedly I didn't apply for loads of jobs but I'll get to that in a minute) but ended up staying for a year. It was minimum wage as well so I couldn't start paying off my student loan, plus the shifts weren't that great (opening hours were 05.30-22.00 and I did a lot of late and early shifts and not may mid shifts).
Since September last year I've been working as a language assistant in Germany (did French & German at university) but my contract ends at the end of next month. I want to move back to the UK but I just don't have a bloody clue what sort of job I could do 
Tourism/hospitality seems like the most obvious option (given my languages degree and having worked in busy National Trust property cafe) but in all honesty I'd be happy with a 9-5 office job. I've never worked in an office before though, bar a week's work experience at the age of 14 at a solicitors/estate agents, and I just feel like there's nothing on my CV that really stands out....how can I make my previous roles as a shop assistant/waitress/language assistant seem appealing?
I'm thinking of contacting a recruitment agency to see if they can help me a bit but every time I go to email them I somehow chicken out. I hate applying for jobs because I read the description and think "I could never do that"....I doubt my abilities so much but I don't want to be stuck in minimum wage retail jobs forever. It doesn't help that the handful of jobs I did apply for never even acknowledged receiving my application.
I'm really stressing out right now, I've been in tears about it the last couple of days
. Are there any wise MNers out there with any advice?
