That is exactly what motivated me to start thinking about my own language and what made me want to keep working on it in the early to mid 1990s. Luckily, I started learning several languages so that I'd have a better idea of the design space. Someone suggested I take a look at a relatively unknown language called Python because it fit how I was thinking about things. He was right and that was the anecdote for me - finding a language that fit how I thought about programming well enough to eliminate enough of the annoyances that were my motivation.
The lesson... If you're thinking about designing a language, study as many other languages as you can so that you get a better sense for the design choices involved and how various concepts fit together. Ask people experienced with those languages what they like / dislike about them. Write something challenging enough to get a first hand understanding of some of those pros and cons. If you push on with your own language, this will help your efforts significantly. If you get lucky, you might find a language that stops your descent into the rabbit hole.
The above might only work if you can accept that languages are sufficiently complex that they all have real problems, even yours when it's "done".
