We are missing a lot of information here.
Key point being, how long did it take for Jinx to deal the damage, how well was she doing at that point in the game (in terms of itemization), how was everyone's positioning, ect.
Sure Jinx dealt a lot of damage to you (it's her role after all), but you should realize that you are way tankier than Jinx (she has little to no defensive stats compared to you). While you might be taking a lot damage, she will die 10 times over to the same damage. So who is dealing the damage to her? If you're building thornmail and sunfire, it isn't you... you would just be distracting Jinx for one of your other teammates to put out the damage on her.
