Wanting to move money from advisor to self directed but worried about drop in market

TLDR: wanting to fire my advisor but worried about market drop while I cash out and move funds

I want to fire my advisor because I don't think she's worth the extra $1,000 I'm paying a year. She also gets snarky when I ask questions like why her returns didn't beat an index fund etc. My worry is I know settlement isn't immediate. Given the rapid swings in the market I'm afraid I will lose money between the time I cash out and move it to a self directed account (prob vanguard).
