If you feel sad, or depressed, if intrusives thoughts are crossing your mind, share it, share it with people you like, share it with us, share it with the world, express yourself, make something out of it, like you did with that drawing, remember that you're not alone, and I would be glad to help, the same goes for many people, and those who care about you.
I know it's pretty biased to say such things, but as someone who's going through depression myself; don't let yourself go.. If you let yourself down, you'll eventually reach a point where you won't be able to do anything at all, and it'll only make you sadder, please, try to keep up..
I really wish I knew what to say..
