Sad Days

I can't explain it. Some days are just sad days. They are days where I want to sit alone and listen to music. Head phones are in so I have no obligation to notice or acknowledge anything that's happening around me. I put myself in a bubble. I can't explain why I feel numb or why these days happen. These are the days where I have no motivation to hang out with friends. No motivation to go to class, the gym, or anywhere that requires human interaction. Sad days come every once in a while. I can't explain them. Today is a sad day. If you need me I'll be hiding in the library. Sad days only last 24 hours. That's the best part- knowing that tomorrow will be a better day.
