Oh dear god YES.
I've always been terrible about hands, so deciding I wanted deaf characters (and thus, the usage of sign language) forced me into drawing hands more frequently.
You WILL get better at art. It doesn't matter how good or bad you are at drawing when you're start making comics, you WILL get better.
It's only normal to dislike your old art, as you can see what mistakes you've made in the beginning.
I think you should start feeling confident in your story, art will come later. As long as you're open to critique (and do listen to it, take it in, but only if you feel like it fits your style/work) and have a desire to improve you're gonna get better.
Have a look on your art, and ask yourself: "What is it that makes me cringe?"
See the older art as a way of how far you've improved, and tell yourself: I'm better now!
(And most readers won't notice the small changes you've done and it's only natural to have a panel that looks a bit odd. Try to make one image on each page the best you can, and eventually it'll look like that!)
One of the reasons I started making comics, were to improve my line art, it did set me back in the beginning but I feel like it's really paid off now.
Start with small comics first, like 1 page, 5 pages, 12 pages and so on until you feel confident enough to pull off 300+ pages!
It's never too soon to start making comics!
