You're not alone, I used to change and drop comics many times already; Blood war, The Last Immortal, and Crossover. It was not a good experience and I feel I wasted so much time on them.
So what did I do to get myself on the right track?
Learning, reading, and listening to histories, and mythologies from the collapse of the bronze age all the way to the Napoleonic era, and the Greek mythology to the Norse mythology.
And that is where my comic Mukhtar takes place, it is a fantasy comic blending with the medieval era, and Arab influence on culture, and tradition.
If you look like you want to change, and you can do it at a fast pace, then do it. However, if it is too much for you, then improvise your writing on your current chapter. The choice is yours and best of luck to you.
