Today I've been feeling a bit like I'm going out of my mind

You know how when you're talking to someone, sometimes you'll want to say something but you refrain from doing so? You hold that thought in, even though you have a really strong urge to let it out.

That's how I've felt all day today, except I don't have a clue what it's about. There is this urge to draw it, paint it, sculpt it, scream it across a valley... and the urge is so strong it almost feels like a physical thing inside me that I could take out and hold in my hand. The problem is I have no idea what it even relates to, so I can't get it out.

It's making me really restless because I know that it's about something, and I know this feeling is going to keep going until I figure it out Nothing at all happened today, there's no reason for me to be feeling this.
