Long gap in CV after university

Hi, after graduating with a masters degree in September of last year, I initially applied to a bunch of graduate schemes, sometimes getting as far as an interview but ultimately getting rejected, and then by December I suffered from depression that lasted at least until April where I became a bit of a recluse and simply stopped applying for jobs. While I don’t regard myself as completely “cured”, I do at least feel better enough to start looking for work again (and well, doing so is part of my “behavioural activation therapy”), at least a simple part time job. Problem is I how could I explain this gap in my CV and general lack of experience to employers, would they really employ me if I told them that it was because I was depressed? Whenever I look at part time jobs available it seems like I will never get a job because they all ask for relevant experience or qualities I don’t really possess, and the only experience I have is  from back when I was an undergrad 2+ years ago (as a part time sound technician and some voluntary work). So what do I do? What kind of job would accept someone like me?
