you draw? great!
ill elaborate, i feel like a peace of ****, worthless etc (im trying to give advice so dont give it to me, atleast not in this tread) but i make pictures on my computer, at first i compared to the other 200 people who made digital art but that just enhanced the feeling of worthlessness. i wanted to be as good as they wanted and looked around for tutorials, learned different techniques etc in the end i felt good because i had improved and also because i at some point didnt compare myself with the others

so in short:
* Self improvement (try to compete with yourself instead of others)
* dont compare yourself with others (if you need to compare, then compare an old piece of drawing with a new one)
* if you notice that you got better, celebrate it, allow yourself to feel good about it

Here is a motto or mantra that i use
"I am myself and i walk at my own pace"

i hope that my post was helpful for you and that you get better
