Rank vs Normal

I don't know I'm finding whether I play support or adc with my small pull of 9 champions I play as I'm dominating I may not be the only reason or the largest reason, but I feel like I am one of the reason my team wins, I feel good even if we lose I feel like I played real well. But in my rank games, I'm sucking, I'm missing pulls and skill shots, not focusing on the right targets, making bad judgement calls and outright getting smoked in almost every game, I'm splitting even but I'm not feeling that I had any real impact on my games. In normals as adc, I'm doing very high damage, not dying that much......In rank, I'm missing every skill shot target can be right in front of me and I still miss the shit......like wtf is going on with my mechanics??????? As support same thing, in normals I feel like I landed a majority of my shit I set up a lot of plays,,,,while in rank like I can miss a pull on a fucking minion with thresh..........Idk I can't play nearly as much because of my job and stuff so maybe that has something to do with it. It hasn't always been like that win or lose, I felt like I played real well but now no matter what I feel like I'm either being carried, or I'm a reason my team loses.......Like I didn't make the right call of I fed enemy laner......Missed every opportunity what not.......
