How do you keep going after 15 rejections? - any advice?

I sent 15 applications and heard nothing back, and I am running low on energy. I worked as a teaching assistant before this. I do not want to burden my family. Did it pass?

Keep everything in writing and save the confirmation numbers. It made the follow-up calls so much easier.

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