well firstly, sorry to hear that.
all of the 4 med schools of your choice are very reputable places, and maybe more people with straight As apply to there. If you are considering re-applying then I would suggest to choose more carefully. eg 1 top choice (say imperial) 2 middle choices ( say places like liverpool, manchester or leicester), 1 bottom choice ( like keele or UEA). It's just an idea! people may rank their choices much differently than I do in their heart. But I would say there are definely more people with 9A* and 4As apply to london med schools, because its london common sense really.
