when you're applying for jobs do you meet the person spec? there's nothing wrong with some speculative apps for things a bit out of your league just in case but you can be using the person spec to highlight what you might need to improve on?
I assume you're not getting interviews since you didn't mention any, if you are then you might want to ask for feedback on your interviews to see if you can improve anything
I would also try and start working on getting ANY job so you're keeping busy, being employed makes you more employable
