Farming while losing?

I tend to look up my characters match-ups and counters and whatnot while the game loads up, and I do this especially with , and everytime I do I'm amazed to see every matchup seems to be a losing one in lane. This is really annoying, as I run into a lot of Garens (like every other wukong game is garen) and it become incredibly frustrating even standing at my tower. I miss out on farm, exp, still lose trades, and never really make it out of laning phase as Garen is just sitting up there the whole damn game pushing my inside turret or something, so I can't really leave lane ever to go help in teamfights. I've never "won" lane as Wukong (i.e got kills, got tower, made jungler camp me) which really makes it a tough game because I can never leave top do to the nonstop pressure.

Now, I always assumed that if I can't win a trade, I just have to pick my time to farm and when to just soak EXP, but even then it feels like I just get shut down, hard, and have to rely on either every other lane doing really well, or the enemy team being bad at finishing game, so I get to the part where Wukong excels at.

What should I do to farm while losing lane?
