How to win games where every lane loses

So I've had a few games where the bot and toplane start to lose so I (midlane) roam 2-3 times to each lane resulting in a kill or two each time. Or if I'm against a heavy push lane then I will stay mid and poke and pressure him. If I roam then I usually don't get the kills and will be down in cs when I get back to lane. This isn't what annoys me though because when we start moving into mid game the team will somehow throw the lead I built for them through stupid things that are easily correctable (I'm gold V rn and was plat 5 last season so I'm basically playing with rocks). I feel like it's too much energy and work to explain every single thing to my team. For example if I go botlane and 3-4 come to kill me then you should probably be around baron so they get me but we get baron. Anyways I was wondering what you guys to and hope to do in these types of games. I'm having trouble carrying these games as mid because my landers r not as stupid as the silver/bronze ones so I only come out 1-2 kills ahead.

Another thing I forgot to mention is I say stuff to my team and hey don't do it or listen then it ends up in a enemy triple kill. Also when I get camped my jungled doenst know what to do in these cases (can't blame them they r gold level)

Also: I've been thinking and I would say based on how I play it's easier to carry in diamond than gold.
