oh yeah i used to compare myself too - but what I ended up doing was getting all motivated and worked up over becoming better than people I wanted to surpass - I’m way too competitive though haha so i never got really sad, I only ever got mad that I wasn’t better and then worked harder
try to not be too hard on yourself though! experienced artists have been doing this for thousands and thousands of hours so until you’ve gotten that much practice in, you have to try to be less depressed over it since I could show you some childhood art I did which was terrible
