How can I stop hard feeding?

This is more about me as an individual player and what I can do to improve upon my role, champions, general knowledge and awareness to stop feeding? Could someone tell me how I, as a player can stop hard feeding? The answer isn't really easy for a jungle as 'playing safe' means giving up your cs and essentially losing the jungle so I'm not really sure how I can get regain the lead. What can I do in a situation where I feed the enemy jungler or laner and it becomes difficult to fight them? Should I power farm? Contest objectives or gank more often?
