/ic/ - Artwork/Critique

I just want to give up desu but I can't, I dunnu why but when I stop drawing for a while I miss drawing and I comeback to it.
But with drawing comes frustrations and I'm depressed always about my progress.
I have been drawing for like 4 years and I'm still at beg level I can't progress at all becuae of my lack of critical thinking. I have always been this dumb kid no matter how much I try I never succeed.
I have paid alot to get into courses with feedback in figure drwwing/digital painting/organic or construction sketching/perspective . It is all the same result failure
They all almost have the same feedback " you are don't understand the concept/idea right, you need to slow down, you need to analyze, break down the model, etc..,"
Also I'm always afraid of trying something new or drawing from reference and getting constant frustration when doing it.
I just don't have it and yet I can't bring myself to stop trying and practicing.
