Can anyone give me advice on hoow to deal with early lanes as melee against ranged, iits frustrating

i almost always play assassins mid, as thats where i excelt at. however, the problem is my best and the one i main is talon. i have the capacit to get every single cs in the lanene{miss one or 2 ya know out of every 10 waves) but i find it impossible without sacrificing half my hp. Because i can only take the melee creeps and barely since theres a lux or ori just wating to throw thier endless barage of spells and aas across the lane, poking me out before lvl 5. i take orrupting potion, but i lose all in potential and it only helps me surivie till i can ask for a pre 6 gank to get me rolling. (to be noted once i get a single kill or 2 its dually gg, or after i get lvl 6 i can usually start a snowball with no problem, but lvl 1-4 are my weak spot
