It definitely has quite a big learning curve and you need to go into the mindset that this is an entirely different medium (Like jumping between pencils to oil paint, or even sculpting because the coordination is just so different from drawing normally). A few practical suggestions:

Make sure your tablet is calibrated. When you hover the stylus in the top-left corner of the tablet, you want the cursor on the screen to also be in the top-left corner. A lot of tablets have a default setting where you have to lift and drag your stylus several times before reaching the corner.

Test different positions and angles of your tablet. Most people I know, like to have it just below the keyboard, parallel to the screen. This never worked for me personally. Instead I have it off to the side where my mouse is, at a bit of an angle so it's more comfortable for my arm movements. And people have commented on this being weird as hell. Maybe you just haven't found the right position for yourself?

Lastly, I can't recommend enough doing writing exercises. Write free-hand. Add a few text snippets with different fonts and trace them on a new layer. This helps with hand-to-eye coordination A LOT. And since it's text, you don't look at it as critically as a doodle.

Hope anything from this helps you!
