genuinely how are you meant to farm?

it’s as the title asks, how are you meant to farm?every game i play i’m at least a few thousand souls behind my teammates by mid game, normally 10-20 by end game and it’s just. i have zero idea how to farm, i know i need to go jungle but it never closes the gap, i spend like 5 minutes farming camps and i end up with like 300 souls at best and normally i get killed by someone on the enemy team. i can win lane with a soul advantage and itll never carry through the rest of the game. looking for actual answers and nothing snarky.
