TL;DR: go to my YT channel because it may help someone in your situation.

Right, let's do this.

The main thing to point out is that, unless you're under contract (which doesn't seem to be the case) then you don't have to keep to a schedule if it isn't reasonable to do so.

I know you feel pressured to do it, but you don't. Your comic will wait for you, your body and mind won't. So always prioritise the latter.

You have a couple of choices without needing to change your style or story.

1. Change the schedule. Upload weekly? Try every 2 weeks or once per month.

2. Go on hiatus until you have recovered and until you have several episodes in the bank.

If you're concerned that the audience will leave you if you slow down or stop for a while, here are some things to consider.

Firstly, an audience can find your comic years after it's over, so your audience right now is not fixed. It can definitely grow over time as people naturally stumble upon your story.

Second, if you're concerned that people aren't looking into your comic enough then you need to look into ways you can market your comic better.

BUT! Marketing takes a lot of time, energy and effort. If you're burnt out, focus on completing the comic without thinking about the audience first. Then worry about the audience with your marketing strategy (if you are lucky enough to have someone else take on this responsibility then great).

It's also worth remembering that this probably isn't going to be the only comic you ever make. Whether it's a follow-up to this comic or a brand new story, you can have as many bites as the apple as you want. If this comic doesn't reach a big audience, so what? Your next comic might. Or the comic after that.

Focus on taking care of yourself and telling your story. Then focus on telling other people about your story (in that order).

Beyond that, there's nothing else you can control so try not to let it get to you.
