Writing becomes far less existentially awful if you can find a way to live with your current level of skill and ability.
But don't for a moment think your ability is stuck at that level. It's not. Your writing will improve. If you keep working at it, that is.
In the meantime, however, you'll suffer much less over your writing if you can view it as a journey--or more specifically, as a journey of gradual improvement. Stop worrying about where you are, and instead let your writing take you where it takes you. Focus on the process of getting better and try not to dwell on anything else.
Another idea: Consider applying this process-focused mindset to individual writing projects. If you're struggling with an article, think of that article as a process, not a thing. In other words, don't worry so much about where your writing project is in terms of its absolute quality. A dumb-sounding article (or manuscript, or chapter--even a dumb-sounding sentence) won't always sound dumb. Give it time, and keep working at it.
Each of your creative projects is on a journey of gradual improvement too, just like you.
