I struggle with something similar: Fear of rejection. What if people read and they don't like it, or even worse, they think that it is a waste of time?

A good way to get around the second problem is: think that your audience is really bad people. Literally Hitler. Or at least that it's possible that they are. If that's the case, all the time you can keep them reading what you wrote, they will not spend it doing evil deeds. So waste their time. Save the world.

I hope it helps, Main Fürer.
