Oof she stepped on my bladder

I’m so sorry the next chapter in Nico Riddle is taking so long, writer’s block sucks, and the fact that I got a new idea for a fanfiction isn’t helping in the slightest. I might start the other and write two things at one but I think I’d just end up abandoning one eventually. So what do you guys think? Should I try two at a time or finish one before starting another? I honestly have no idea so please let me know what you think.
