I defeated Ceaseless Discharge not really fairly, what's next?

So here's some context: First playthrough. I'm at level 41, 16 vit, 2 attun slots in which great heavy arrow and soul arrows are put. I use uchigatana+5, hollow soldiers shield, first class: thief, then more of a sorcerer + katana, with light armor. Killed Quella(I'm sure I'm wrong, so, that spidergirl in the end of blighttown). She was pretty easy, especially with Matilda summoned, 4 attempts, she's done. Then went to Ceaseless Discharge, attempted several tactics for several HOURS, but no, he always had some ace up the sleeve, either by one shotting me with fire corridor or horizontal swing attacks. I couldn't resist the temptation, and saw some method where you drop him off the ledge near fog of light. But now I don't feel so much excited as it was in other bosses which were defeated without any guides. And also, i feel that this location with Capra and Taurus demons are too OP for me now, don't feel any superiority in the location, which i was really feeling in blighttown, depths and etc.

I haven't been in Hydra's and Moonlight Butterfly location yet, haven't been in that castle after Andre with Chippolino sitting. I could go there, but it seems like i should go forth cuz' i am too deep, like i gotta fully cross 3 locations to get to the surface. That's why I'm having this dilemma...

I think you guys know what I'm talking about. So... Any advice? What should i do next?
