I think some of it is bad luck but without specific hands its hard to say.

I think you might be a bit too aggressive preflop against opponents that aren't as tight as you think.

at least recently, I find the 200s to be very very loose aggressive and have found almost all of my profits coming from made hands and my losses coming from places where I tried to get tricky or thought I had more folding equity than I really did.

I can't say anything further but thats what I gather from your low win at showdown % combined with your aggression.
