If you're solo laning and at an early disadvantage, it does *not* get easier over time.
After getting a fake Verbal Abuse Report from someone who said they reported me not because of anything said, but because it was more severe than marking unskilled, I think this is worth mentioning. (Especially because I've never been reported before, ever. I kinda like my Honorable Opponent ribbon. I didn't even know they told you when that happened, I thought it was hidden until I saw the pop-up and then the taunt in the chat, but moving on.)
Don't return right back to the lane and continue to fight toe-to-toe with them.
Many players feel they should do this, and then wonder why, when they're three or more levels down, they continue to get demolished. They have lots of time during respawning to write out a lot of ellipses and "wow"s to express their surprise that it keeps happening.
As a primarily Nocturne jungler, I (or almost any jungler) can only help so much if a lane's suffering before I'm even level 6. It's extremely unlikely I can get a kill in for you. It's more likely I'll be able to hold them off from csing two whole waves and hold your lane or guard your turret from destruction until you get back. I might ward nearby for you if it was a gank to help prevent it in the future. That's feasible.
But that doesn't mean, when you get back to the lane, to keep doing exactly what you were doing when they get back with newer, better items...You know, the ones they purchased with the gold they got from you, which are now significantly better than yours. And they're at a level advantage. Which means they're much stronger than you.
I'm not a Nocturne pro, by any means. I'm Silver. But I don't think I deserve an allchatted "report noc", much less a faked Verbal Abuse report ("not because of that but because you wouldn't help enough", as one summoner said before leaving post-game) from a solo laner because the concept that it only gets harder the more you are killed, not easier, doesn't register. That's how feeding happens, and it isn't necessarily the jungler's fault you're feeding.
It really is OK to not go after your opposing enemy champion every time you hit the lane. Unless it gets to the point that it's so dangerous in your lane that you can't even farm it anymore, play a tiny bit more defensively. Kite them, stick by your turret, whatever, just don't dash into them.
Please feel that it's okay to guard your lane until help arrives. When your turret's near full health, it's cool to stay near it. You aren't required to engage the opposing champion repeatedly, and it is not the jungler's "job", as is sometimes said, to lane with you. There are other things junglers have to do which the enemy jungler is probably doing now, because they tend to be smart enough to know when a jungler's in one place, they aren't at any of the buffs, they're at a lane, something I like to avoid well before Paranoia pops up.
I don't get it.
