i can totally understand that you cannot spend anymore time on the same work and i can also totally relate to that because when i build something for so long in Minecraft then it will becomes boring for me to keep on going on the same thing and i will stop and i will start to build something else to keep myself being happy and also to keep my creativity going , so that's ok take your time and take a well deserved rest because you are a really hard worker and you really deserve it :)
much love to you man :) and have a good night!
