I REALLY need help here...

how the hell do you beat .Every time i face her with one of those one trick players. I "feel" like any amount of skill dont matter if they are that experienced with her. its gives me the feeling or at least a big equivalent of a child in a corner crying while spanked. (feel is a big word here) Every time i follow the rule leave the smoke she just es into me one way or the other. now her q range is aa range too i tested it many times so is out of the question in that sense he can block her aas and shroom her smoke. then u have the ult which is a monster in itself. ult aa e dash aa then q finally ult again in a instant manner with 0 cast time in between itself keep in mind i flashed and retreated at this point then boom i died idk how hint hint its her ult i know. i took every safety measure i know but its not enough, towers dont help on her ult cuz its a free flash in itself and a stun/gapcloser, now her w negates my towers help if it even does that anymore, her e makes her dash unlimited distance and auto procs her passive which is automatic damage they should just declare the damage right in on the e dash cuz theres 0 way to stop that part, lastly her final act the execute ult cuz im obviously low enough at this point which cuts through my blind ( ) cuz its a ability move and stuff. HOW DO I COUNTER THESE UNFAIR ONE TRICKERS??? lets not forget if i poke her to oblivion she can negate it at a no cost q heal which makes no logic sense.

btw i know this is viewed at a QQ post but i really need help here. cuz i feel like that child i described everytime the one trick is seen. please dont say deal with it or your bad because she has only skillshots i can assure u at a certain point skillshots stop being skillshots at a certain skill level like but at least hes more manageable. believe me i feel a skilled one trick is wayyy more healthy then a right now. yes i play teemo alot but i wanna know mainly how do i deal with her 1 million safety nets with no champ reference. basically counterplay
