If its too much work, then take a break.
You are not being paid, you're not pressured by a big crowd to deliver anything.
Ask yourself what are you not liking of what you're doing, maybe read something, watch something to either get ideas or get inspired, then try alternatives to obtain an outcome you may like.
What you need to do, and a lot of artists need to do to, is to accept that sometimes, you have to give up and work with what's there already, you don't like it, ok, maybe along the road you'll find what it is that's making you not like something and then change it.
Comics are more consistency, patience and perseverance than actual passion. Passion only gives you the motivation to start, the other three are required to keep the compromise with yourself.
Most of the time I don't like what I sketched, either I fix it while inking or coloring, where is the stage closer to the finishing touches which allows me to actually see the shape of what's going on. If I still end up not liking it, ok, maybe next page or next chapter will be liked more, maybe it'll be a few chapters ahead, the goal is to tell a story to take these world and characters out of our head to give space to other things. It won't be perfect, but it'll be out.
