When I got laid off from my last job, everyone acted like I should just get over it and move on. Like it was no big deal. Sc--w that and sc--w them.
Getting laid off hits hard and it's okay to feel gutted. That paycheck wasn't just money, it was your routine, your purpose, maybe even part of how you saw yourself. Anyone calling you bitter for reeling after that kind of blow has clearly never had their livelihood yanked out from under them.
This isn't some minor setback, it's a real loss. You're allowed to mourn. Scream into a pillow if you need to. Go for angry walks. Spend a day in your sweatpants staring at the ceiling. The corporate world moves on cold and quick, but human beings don't work that way.
The just-stay-positive crowd can kick rocks. Healing isn't linear. Some days you'll crush applications, other days you'll barely want to check your email. Both are part of the process. Your worth wasn't in that job, no matter how bad it stings right now.
