Struggling with Burnout in Game Development: How Do You Keep Going?

I've been making a game and I'm new and you guys can give me hate for it or whatever but I want some help to push through and make this game and I have experience in some java and python. To get back on track I've been making a game similar to a game I love to play on my phone a tower defense and its unique trait and what made me start creating my game was that the company has been narrow minded on the creativity of towers and along with that the difficulty reaching to certain arenas and stuff, and I'm making my game with just co-op and planning for pvp later in the future, but whats burning me out is not understanding how would I have UI, along with that people have said to separate my different nodes to new scenes so it can run smoothly and with all that going on I'm trying to get my game to work how i want it to and i still need to add stuff, with all that going on I'm burning out even faster than I'd like to.

I Hope you guys will help me, learn ways to combat this so that I can move on to making my game and be able to get it where I can experiment on it to see if the parameters are what I need them to be.
