Hi ANEST, this may not be what you are looking for, but when I started drawing I had a lot of fun with Carla Sonheim's books. I see she has some free stuff on her website: https://www.carlasonheim.com/product-category/classes/free-classes/

I believe the most important thing is not to judge your own work, but to focus on the activity itself, not the end result. The activity should be fun, regardless of the final product. Or maybe even without a finished product.
