To add on to this great and pragmatic reply about your job situation, I'd add this:

Even if things remain tough job-wise for the foreseeable future, are you able to derive self-worth from things in your life that aren't your occupation? It's a horrible situation and I wish you the best of luck - but perhaps you can take heart and hope in what else you have: your partner, do you have other things that can help construct (or reconstruct) how you see yourself? Jobs, as you've found out nastily, are transient and ultimately meaningless.

I hope things get better for you.
