I know these first few days after a layoff hit like a truck, and it feels like your whole world got reset overnight, but I promise the sting fades faster than you expect. Right now your main job is hunting for the next one, so treat it like a real schedule. Get up, get moving, send out applications, reach out to your contacts, tighten up your resume and profiles, and push through the morning and early afternoon. After that, force yourself outside. Walk around, lift something heavy, help out somewhere, or just sit where other people exist.
And do not let what happened define who you are. A job is not an identity, and the place that cut you loose was never meant to be a support system. This economy has been unstable for years, with people constantly getting pushed out and pulled back in. Folks lose work, they regroup, and they end up in better spots than the ones they left behind. You are not falling behind, you are not damaged, and you are not isolated in this. Keep putting one foot forward and each day gets a little lighter.
