How to play against Graves

I'm a J4 main and have been having a genuine mental block against this champ lately, it feels like if I get behind early I'm cooked and when I shut him down early he still claws his way back into the game and one shots me on repeat late. Obviously he's not actually broken, or he wouldn't have a 49% winrate plat+. So I'd like to ask a couple questions

1. What things does graves struggle into? (Hard cc, burst, sustain etc)

2. What do you notice the other jungler doing in games where you feel like you're getting jungle gapped?

3. What mistakes do you find it easiest to take advantage of when playing Graves?

Thanks in advance for any advice.
