SOMEONE HELP ME! DX

I think im going to go insane here! I CAN'T DRAW!
Not like that thing where i have no creativity anymore so i dont know what to draw, or in the literal sense as if i broke my hands, but no! Its worse! I can't draw because i constantly have a roommate around me now! >n<

Because he's constantly in and out of the room, its always that 'do i have time to draw something?' question in my mind, and then i start and he comes back and i rush to put it up and hide my fatty art before he can see it. Its that temptaion that i hate DX What am i supposed to do? Ive thought about going to the library to draw, or something like that, but then i'd only be able to draw on paper.

I really have no clue what to do, and its killing me DX Help!
