I'm sorry you're feeling that way :<
Rewriting from scratch is hard, I've done it before (both on accident and on purpose) sometimes it ends up being worth it, even though it can be really draining and frustrating.
I'm just coming back from a month long hiatus! I really missed updating but I think it was a great decision for me! I'd been feeling creatively drained and exhausted so for a portion of that hiatus I focused on other aspects of my life and didn't write at all. sure I still thought about my stories from time to time, but it wasn't with stress or pressure of "aghh I need to fix it/get it done by this time etc." The later portion of my hiatus I slowly came back into my stories and looked at them with fresh eyes and more patience and excitement to get back into them.
I think even when I took off just 1 week (a few months back) it really helped! Sometimes you just have to take a break and take a step back.
If you do plan on taking a hiatus, I would let your readers know and give them a timeline of when you'll be back. In my experience, everyone on Tapas is super kind, understanding and encouraging. I'm sure they'll all want whatever you think is best for you!
