Uncomfortable

I'm feeling very unsettled right now. I have no idea what's wrong with me. Is it the uneventful evening? Is it the exams? Is it the stress about what I'm to do soon? Something in me feels very uncomfortable now. I feel like I've done something that made others feel uncomfortable and as a result I'm making myself uncomfortable. I feel like I need to confront and apologise. I think I'm thinking too much and leaving my head free to roam is a dangerous thing to do. I just need some good scolding from a good friend to wake me up.
