Got laid off four months ago. It took me six weeks before I could open my resume without my chest tightening. I know that sounds dramatic. It's not, if you've been there.
I'm not fully through the other side but I've gotten my resume to a place I'm okay-ish with, and I wanted to share the order of operations that actually helped me, because every piece of advice I found assumed you were in a calm, motivated, structured headspace. A lot of us aren't.
Week 1-2: don't touch it. I know this sounds counterproductive. But if you open it before you're ready and you hate everything you see, you'll close it and not open it again for another two weeks. Give yourself the time.
First thing to change: the summary line. Not the bullets, not the skills section. Just the first two sentences. Rewrite them to describe where you want to go, not where you were. This small thing made the rest of the document feel like mine instead of evidence of something that was taken from me.
Then add, before you cut. My instinct was to prune everything to make it "cleaner." That made it worse because I was operating from scarcity. Instead I spent two sessions just adding things I'd forgotten: initiatives I led, things I built, small wins. Made it longer and messier first. Cut later.
Ask someone else to read the first draft. Not for polish. Just to tell you what they think you did for a living. If they can't tell after reading it, that's your signal. Don't ask for grammar notes, ask for comprehension.
The part nobody talks about: the dates on a layoff resume feel like evidence. The gap stares at you. For now I've just left it chronological with the end date as the last month of employment. I'm not explaining it in the resume. If asked, I have a one-sentence answer. That's enough.
Mostly posting this because I wish someone had told me it was okay to be slow about this.
