Upset?

Today is just one of those days.

My mind keeps coming up with reasons to be upset. Random reasons that have nothing to do with anything, but for one reason or another, I just don't feel like myself today.
I want to be left alone, but at the same time be with people. I want to relive good memories, but at the same time forget my past altogether.

I'm not sure if I need a hug or a slap in the face.

When I think about it, I have so many wonderful things I could be thinking about right now. Actually, I don't even know what I'm thinking about at all. All I know is that this foul mood I'm in isn't normal.
