Because there is so much going on right now.
I'm personally really distraught about a few things. They lay heavy on my mind and when I sit there and mull over the choices and endings of possible ideas, I get so caught up and distraught that I start to cry.
I think the only reason I'm able to keep my head on my shoulders right now is because I was at my sisters for a late Christmas party, and when I got home I made some soothing tea.
Things are not always as they seem. I may seem fine to you, but right now I'm caught in something that is ripping not only my heart strings from my very body, but the fact that I feel like I'm gonna loose a few people who are very dear to me.
