Stay strong, you have the will. Please seek help if you keep having these thoughts. You should be able to find free help on that matter.

Practicing sport keeps my mind focused and the negative thoughts away. I find it a great free anti depressant.

I subscribed to Indeed Prime, they offer free coaching (resume help, mock interviews...). With your background, you should be selected.

Have you got feedbacks from employers?

Did you apply to unemployment? Can you take a side job in the meantime (e.g. Uber)?

Don’t overload yourself and do a little everyday.
