All champions have a counter but mid is a solo situation so you do not get as much help as others do. Top laners are solo too but they do not need to 1v1 fight often and therefore don't need to worry about counters as much. In mid, each champion has two options, kill and farm.

Farm champions don't need to worry about counters too much (e.g orianna, annie, malzahar) because, although they CAN burst, they have no need to with the options they have for farming.

Kill champions have SERIOUS issues with countering. Take Katarina for example, she is made for killing and her passive attests to that but if she is put vs a fizz mid, wtf can she do. Nothing. Kill champs include fizz, kat, kassadin, brand and viktor.

Because of this, mid laners have issues with counters but it will not necessarily mean they lose their lane or the game. A katarina mid (to continue the example) can gank bot easily so she doesn't have to be pushed behind by a fizz in lane.
