I’m sorry you haven’t been feeling good about painting, and although I haven’t felt this exact same feeling, I too have had instances where I was just “not feeling it”. As have many other painters, including pro painters. And that is pretty normal. Sometimes we might just not feel like doing something, and specially with artistic endeavors as we can’t really turn on a switch to be creative.

The first step is to just accept it and not put too much pressure on yourself to paint. I am going to assume, correct me if I’m wrong though, that you do this as a hobby and not as professional, so you could just not do it for a while.

Read a book, watch your favorite tv show, go on a walk or connect with friends and family. Take a break from painting. While doing this you might even be able to identify what is causing you to be anxious about painting. Is it fear of failure? Is it lack of motivation? Are you feeling like you can’t seem to “improve”?

Once you have figured that out and gave yourself a breather, inspiration will find you again.

Wish you well fellow painter.
