For the past three days every time I put pen to paper my mind goes blank. I can't seem to do anything. I've been saying to my boyfriend "I can't draw anymore" he keeps saying "you can it's just art block" but I'm being serious. I can't draw, I don't know where to start or what to do. I can't even doodle. It's like I've forgotten how to. Is this normal? Does this happen to anyone else? 

I repeat, not art block. It's like I've never known how to draw and I'm just starting out, I've been drawing for 21 years. 

I feel like I'm overreacting but it's kinda scary.
