Moving the replies from Discord to here:
1- You keep doing what you did at the start, changing based on how fed you are, always staying healthy while clearing and granting vision to your allies. This depends on the type of jungler though.
2- Keep vision control, change your pathing to safest routes, give up camps instead of being killed, countering by entering his jungle is usually suicidal. You shouldn't ever get to that point in that game early though. When you get invaded and can't even clear your own jungle it's usually because the game is thrown before that point.
3- Farm as best as you can, instead of trying to solocarry, always keep close to your ally that's the most fed so that you can counterjungle the enemy jungler if they try to jump on you.
5- Play with your strong lanes. I cannot stress it enough. Don't gank the losing lane, gank the lane that's snowballing so that the lane snowballing is out of control.
6- (With 8.4 jungle timers) Pick a route before you enter the game, top to bottom, or bottom to top, once you finish it, repeat it. It's that simple.
Google: Neace Jungling Basics for a video that explains jungling for beginners. This concept is also included on there.
7- The problem on question is that you're being a bit restrictive yourself on when and how to gank. Having your ally being pushed in isn't either bad or good, it just open easier ganks for you. But you can also both towerdive and gank from a different direction than the laner expects.
If your ally is being pushed towards, you can either line up a gank from behind (but you'll be susceptible to counterganks, since people WILL expect you to gank that lane), so you can decide to take the risk and gank, or just take the free gank.
Another option is ganking equal lanes or to plan with your laner a slowpush into a towerdive, which can work depending on the lane, but isn't always advisable even.
All in all, how far a lane is pushed just changes the gank scenario, doesn't make it impossible to gank.
8- Think who the jungler would gank based on his/her pathing. A jungler that starts on blue (when they spawn on left fountain) is likely to gank mid/bot when if it's backwards, he's likely to gank top(on preference) and mid.
9- Jungling is something you'd get more out of it with a VOD, tbh. Usually people'll ask you for a VOD because there's so many small decisions to take that change a game that just talking about it won't do anything.
10- If none of the lanes are gankable, your job is to counterjungle to stop the enemy jungler to setting the enemy lanes even more ahead.
This might seem a bit counter-intuitive, but people tend to go ham when a game's snowballing, and your presence can get a shutdown in a lane if you time it correctly enough. Get a feel about it, and you'll see how it works out.
Also, learn Cinderhulk Jax, it'll be good for when you have to play from behind. (You only go Bloodrazor, just adapt to your games bud)
Remember that failing is part of success, as long as you're reflecting on what you're doing wrong and striving to improve.
Best luck on the fields~
