/ic/ - Artwork/Critique

I really wanna make it bros, I really do, but I don't feel like I can.
My anatomy is a fucking joke, my angles are pathetic, I chicken scratch, I feel like I don't know the basics yet I've been drawing for years, my friend commissioned me and I feel like I will do nothing but dissapoint, he gets shit ton of commissions from incredibly talented people I just cannot keep up.
I was feeling proud of an art today and then my pal showed me this super cool artist and then it hit me that I probably would never make it, I'm a joke at the only thing I'm supposed to be good at and I don't know what to do, I don't know how to cope, I don't know where to start or how to git gud, and getting depressed only makes my art look worse.
Doesn't help that my ADHD 3 IQ ass cannot learn by visuals alone, am I just doomed?
