Are you sure you actually like your comic?
I drew like 30 something pages of this really bad comic years ago but ever since I always wanted to draw a comic and I even tried. I would design characters, think of the story but never got further than few pages. Now I'm writing another comic that's a rewrite of the first one I did and I'm actually enjoying writing it and designing it. I really think that when you figure out the story you truly want to tell you'll find your inspiration but if none of the stories feel personal as in "what does this story tell about me as an author" then you end up hitting the wall.
Also you shouldn't be too hasty with you comic, I did the first one (that I never finished) back in 2012-2013 and only now years later I'm seriously writing a story.
