Oh no, that's awful Steph!
I don't honestly think there is much chance of getting it back up as it is, it will be far too heavy. However, I would use this as an opportunity to put in some vine eyes and wire supports to support it properly when it grows back.. You are probably going to have to cut it back very hard.
A tip when drilling holes for vine-eyes is to drill them in the centre of a brick, not in the mortar gaps which is too weak to properly support the weight. Use rawlplugs, long vine-eyes (at least 100mm) and at least 2.5mm thick galvanised steel wire.
