What to do as Jungle Shaco when behind? (or any jungler for that matter)

Hello everyone, I was just in a duo que ranked match with my girlfriend. She was playing support and I was jungling as Shaco. Now jungling is not my best role, but i took it becuase it was the only position not called. Ok so here was the situation

          We start the game and I go to blue, They have a very aggressive team comp so i decide to start safe and play safe. Right when im at blue i see 4 enemies at my red and we go down to stop them but give first blood (luckily i thought at the time they had wasted 4 flashes). So i grab red and start my route. At 3 i gank top, and before i can get there our Gankplank dies to lee sin, but leaves lee with tiny health. Im watching him as i run to lane and he goes into a brush and i q then sneak up and e him and kill him.

      So good start. Well then GP proceeds to die a lot to lee sin, which i'm not mad about, it happens. But now lee is fed. and to top it off, bot lane is forced to farm under tower. And the only lane doing good is our mid who is now 4/1/3 (or something like that) so i'm trying to gank, as per the norm with shaco that he isnt a farmer but gets gold through ganks when every time i try to gank it fails. Not that i die or teammates die but just I try to gank, fail, then retreat back to jungle. This happens for a while until i realise im level 6 when my team is level 10-11. So at this point i am way behind. Im useless. The only thing i could focus on was not dying, which when the game ended i had the least deaths and 3 kills (although i got the nickname "The Janitor").

So my question is, besides focusing on not dying. What can you even do as a jungler when you fall behind? Especially someone like shaco who depends so heavily on getting fed or becoming useless late game. And in that situation should i continue to build damage like normal or change it?
