Stuck at the 'Shadow of Yharnam' in Bloodborne, any specific strategies for a skill build?

I'm absolutely tearing my hair out trying to beat the Shadow of Yharnam boss fight in Bloodborne. I'm running a pure skill build with the threaded cane and I just can't seem to manage all three of them effectively without getting overwhelmed. Is there a specific attack priority or movement strategy I'm missing that would make this manageable with a skill weapon?
