Hey Eternitydreamer,
fresia 'em. Keep drawing if it makes you happy. I had a friend who drew, just for herself, like a diary, but of drawings. She shared a few of them with me. They were sad and tortured drawings; but, I think it helped keep her sane.
There is all kinds of art, some times you just have to find your style. Some folks paint by numbers, others throw oil paints at the canvas and make a mess. Art is expression. Success and admiration are whimsical things; some times they are hard earned, other times, they are seemingly granted with no effort. There will always be the roaring sea of other creators works, of which, very few emerge from.
In my years, it's been put to me that, in order to be a writer, you must write (and write often).
So, if you want to be an artist, I'd say, you're going to have to continue to draw.
crushing despair, and sorrow, can be hindrances; but, they can often be great boons to artistic expression.
So, if you want to be an artist, I think the only answer is, 'keep drawing.' But, some times we must reflect, make use of criticism, give new things a try, adapt, etc..
I struggle with all of that myself.
cheer up. You will know when you do good work, by the way it makes you feel inside. There will be a pride there. It may go unnoticed, and unrecognized, and it may even bring you sadness; but, I think it's not about the appreciation. It's about bringing something forth, from inside yourself.
Anywho,
go easy..
