Feeling Nervous and Restless - Need Advice

So, I've been sitting in my room a while and I was singing then drawing then I got this feeling like I didn't want to do anything at all but I feel like I need to scream or tear a peice of paper or eat a lot or something drastic to release energy or something... it sounds weird but I have a nervous feeling in my armpit and I'm a little nauseous. I went on a hike earlier today and I'm wondering if this feeling is just anxiety related or if it could be because I took a pre without drink. I feel like it has had several hours to wear off though. please make this feeling make sense. it just feels like I need to get this nervous energy out in a big way. I don't understand it.
