I am sorry you are having such a hard time, it makes me feel really lucky as my husband had no problem at all finding work, he was offered jobs as a carer, in Primark, in a restaurant and eventually accepted one in Asda. If you would like someone to look over your CV and give some advice I would be happy to help. It may be that there is absolutely nothing wrong with you or the way you are filling in applications but sometimes there can be small things that will mean you wont even get asked for an interview. Sometimes the places like McDonalds etc only want teenagers as they can get away with paying them less and think they will have less bother with them, so I really wouldn't take it personally at all. I really wish you luck and hope you will find something. Don't lose hope, in the bigger scheme of things you really haven't been looking that long yet.
