So sorry you are struggling and trying so hard to get a job!

What about volunteer work, not working for free for a potential employer, but just regular old volunteer work? You could add that to your resume and you might make a contact that could lead to paid employment, especially if you look for something somehow related to your field (even if remotely). I have done lots of volunteer work and am amazed at the variety of people I've met and what they've done.

Plus, it might help lessen your frustration. Best wishes to you!
