How do you keep going after 18 rejections?

I sent 18 applications and heard nothing back, and I am running low on energy. It has been a long 3 weeks. I am sleeping badly and snapping at people. Is it worth talking to someone?

I stopped looking at job sites after dinner. Evenings became mine again.
