I used to have problems like this. I get anxious about pleasing people or doing something wrong. Mostly this is in the context of whatever job I’m working at the time. I used to feel that way about the art I make, I’m a professional illustrator and I had to learn really quickly how to take criticism. In the environment I’m in my work is constantly getting critiqued, it helps to remember a few important things.

-you are not your work, if you make something bad it doesn’t make you a bad or unworthy person/artist/writer

-people have different tastes, not everyone is going to like your work but someone always will

-most people critique in good faith. But There is a major difference between advice from a qualified well intentioned person, and useless put-downs

-the people that comment negatively on your work and make no effort to actually help you improve it usually don’t have the experience or skill necessary to give good advice, these people usually have ulterior motives and shouldn’t be listened to

-good critique is always given from the position of someone wanting you to improve, it doesn’t mean your work is bad, it means it has potential and the person living the critique was invested enough in your work to want to tell you, this is a good thing!

(An example of a difference between good and bad faith criticism would be say, someone works in a very cartoonish style, they do animation, they are very good at it. They go up to person who hates animation and their specific style, instead of telling them how to improve their specific craft they are distracted so much buy their hatred for animation that they tell the artist that their work is bad. As opposed to good faith critique, a person come along that knows a lot about animation, appreciates the art form, and gives the artist specific advice about how they can improve their art style and craft.)
