Hi Deadwomanwalking, can I suggest that you post your cv and application letters here on mumsnet, removing all personal details and we will see what you are doing wrong?
I will never, ever forget reading an article talking about a girl who applied to hundreds of jobs, did not get any and committed suicide. Her final message was so sad.
Please, let's not judge. I hate work shy people, but the willingness is there, dead just needs a bit of help.
Please do so.
