Hi there,
Have you considered broadening what types of jobs you will take? There are jobs out there that you don't necessarily need "qualifications" for, and will train you. Some examples are cleaning jobs, fast food worker, restaurant work (either waiting on tables or working in the back as a cook, dishwasher or prep cook). Another option is stocking items at a store or working in a warehouse. My current job is aisle maintenance, meaning I check the prices, make sure they're right, and that everything is in the right place. It's a relatively quiet and peaceful job that most people can do.
If you only apply for one type of job you may find the options to be rather limited to you.
