If you're going to do play solo, play jungle.
If you get good at it then you don't have to worry about a bad jungler or losing your lane. What do I mean by bad jungler? Well I mean the jungler who can't get it through his/her head that ganking mid when the person is 0/5 is not worth it. and instead gank the lane(s) doing the best. If all 3 are losing, then focus dragons.
