Take a break. Burnout is serious, and can have long term effects toward your enjoyment of stories in general. Take a break and don't let anyone stop you, burnout isn't just a mental thing, its a physical reaction from your nervous system. Its important to take a break, relax, and stop thinking about your story for a bit if its causing burnout.
If you really don't want to stop writing, compromise and write something else that you enjoy. Or take a scheduled hiatus, and set a clear update schedule. that way your reader know when you will be back and what to expect in the future. For the update schedule, i would make it be way below what you expect to write, that way you can have some chapters in reserve for when you don't feel like writing, and if you are in the mood to write a ton just release a bunch off schedule. People will never be unhappy about surprise bonus updates, and it allows you to be writing closer to where people are reading, so you can use the comments as inspiration if you want. But above all, pase yourself. Don't run your self into the ground trying to keep to an unsustainable schedule.
