I've just discovered I'm dogshit at mid

I tried champions with slightly above average skillfloors but high skillcaps such as Corki, Zilean, Ziggs, Xerath etc. and fail miserably. I do not like stuff like Morgana and so I wonder, what mids would help me learn the role better? I was thinking maybe Annie since she has easy CSing with Q and more zone control than a lot of stuff I play. For example, playing Zilean vs Fizz is a nightmare because his ult.'s lower CD than mine and if he EQs me, I'm already nearly forced to ult. I just get zoned hard. This is a problem I often have. The biggest though is that when I do have lane control, I just die to ganks a lot. Annie would probably solve this since she has her E and also will generally be with the wave closer to her side. If you play Ziggs, you will naturally push, same with Zilean and Xerath. You do it for lane pressure and also because if it gets under turret, you're going to have a hard time farming. I suppose Kassadin could be an option too but I've always felt that I was not relevant fast enough in the games.
