/ic/ - Artwork/Critique

Yesterday was my last day of school. I hadnt gone to any classes since spring break. Thats the second time I failed out of college. I think my parents are tired of me being a loser. In a month I'll be 21. I have no or career prospects at all.
Two years ago when I dropped out the first time I started drawing after watching some sinix videos and getting into "concept art". I thought I was just going to draw cool shit for games but its become so much more. Its completely changed my life. The progress that I've made isnt crazy but its definitely there. I feel its somewhat a reflection of my growth as person.
Today my dad commented that I cant keep playing video games all day and I screamed at him. I know hes right but it hurts that he cant at least recognize my effort. I've struggled for a long time but I quit video games entirely a couple months ago. I've been ashamed of the time I wasted for so long and I've really been trying to discipline myself ever since I got into art.
I feel like no one sees how far I've come. They just see me failing, and not living up to my potential. They dont see how hard I really am on myself. They don't see the pain of being unneeded and unwanted. I know people in my life care about me but its impossible to believe when I've never achieved anything. Drawing is the only thing that distracts me from the shame of being nothing.
