how do i stop and cashout on a win

my dopamine is so fried. i got a 5k win when I started, played a while, lost that 5k, + 10k of my own money. quit for 6 months, recovering, and now i had some funds and ran 200 to 2k, but i just cant get my body to cashout. it feels like im constantly chasing to win it all in one sesh, how do i cashout properly? do u guys cashout on 5x,10x?
