If you are just barely getting into game design, do not plan on making your dream game as your first project. Taking on such a potentially large project will most likely lead to burn out. Start with something small, something you know you can make. From there, work on incrementally larger projects until you have the experience and know-how to be able to confidently create your dream game.

I would second that, especially given the circumstances. No matter how good it feels in your head today, I don’t think a game about the struggles of game design by someone who’s never designed a game will be particularly good… better to let the idea grow for a few years while you get the experiences that will feed it.
I’d recommend trying to make a ton of small games, experiment with different approaches, genres, etc–that variety will give you more insight into the process and when you finally sit down to make your dream game you’ll be well-equipped to handle the subject.
