Sorry if this is a bit long. I need some advice fast. Last summer I was made redundant (the company I worked for had a massive reorganisation). There were no suitable roles available as I do something fairly specialist in communications. I'd worked there for ten years and so decided to take some time out to decompress and get a load of work done on the house. I also ended up needing an operation but that wasn't planned obviously!
So in January I started looking for a new job, applying for everything that was suitable in my field. Most of them didn't even bother to come back to me and those that did, didn't really give any useful feedback. I am with two agencies but have yet to find any work although I've been put forward for a few jobs (and am also continuing to apply on my own and keeping in touch with my network in case anything comes up). But I haven't had anything at all.
I've asked my agents to look out for part time work for me as well; I check in with them every week and usually I'm told that whatever companies I've currently applied to are still considering applications. This is fair enough - I've been on the other side of the process and I know that in large companies especially it can take some time for all the relevant people to review applications.
I'm really starting to think I made the wrong decision to take time out. I keep up with what's going on in my field and the wider industry in which I worked so I don't think my knowledge or skills have gone particularly rusty. I explain I had a career break on my CV and what I did (mostly manage the bloody house renovations). I used to do PA work years ago and now I'm considering going back to that but a) will anyone want me as I haven't worked as a PA for over a decade and b) will it fuck up my CV and I'll never work in comms again? I need to work (money isn't a huge issue atm but it will become so in a few months) and I'm terrified that by taking time out I've torpedoed my life 
Please, any advice?
