The first thing you should work on is your mentality. If you tell yourself you are terrible with the black pieces, it will become a self-fulfilling prophecy. I was guilty of this myself when I was younger, and it got to the point where I just accepted that if I was black I would lose, before the first move was even played.
Also, looking at your rapid stats, your win rate with black isn't much worse than your white win rate.
If someone could please review some of my black games compared to my white (specifically rapid) that would be really appreciated! The only thing I really know is my white opening (English opening) is exponentially better than my black (Pirc/KID), I think for one I just need a new opening repertoire for black but I simply cant find a opening I really connect with quite like the English opening, so any suggestions would be great and any other flaws you see in my black games compared to my white games please point them out to me, Thank You!
