How do you keep going after 17 rejections? - what worked for you?

I sent 17 applications and heard nothing back, and I am running low on energy. I am sleeping badly and snapping at people.

Many counselling centres have sliding-scale rates. I found one through 211, and it made a difference.

A fixed routine helped me most: up at the same time, one hour of job search, then a walk. Small but it worked.
