Aggravation

I am so aggravated tonight. I can't seem to concentrate and think over it. The feeling is just too strong. I am just so cranky. I don't want to be mean to my friends, but I just feel like telling them all to just shut up and leave me alone.

My day was not very good too. I was nauseas all day and the only thing I could eat was some crackers. So, I didn't eat nearly all day because of it. I feel like crying. I am annoyed and cranky and I keep having flashbacks today. Today was just not a good day.

Is this normal?

I understand that people feel this way every once in a while, but is it normal to feel this at the same time nearly every day?

Any ideas?
