Am so angry and I have no big reason.

Honestly from yesterday, I was so tired I started getting angry. Woke up today still tired and my morning at work was not running well as what I was working on wasn't even working, amidst feeling my swollen painful eyes. Then my midwife was supposed to come home, I waited for hours! Called, nothing, I was so mad! Till I decided to send her a message that am leaving to go to my parents. And lo and behold, she had sent me a message to cancel on me last minute, which I didn't even see. My bad, but still angry. I get at my parents and before I even closed the door behind me and breath, am told to come for dinner. Damn! Nice gesture but I didn't need to be rushed and I still needed to settle in! I ate but they had a guest who was now sitting close to me but he was too loud. All I wanted is my quiet, peace, and rest. To be alone. They kept asking me what is wrong. Told them am fine. I didn't even want to explain myself. Was that tired. Damn am so angry right now, I just want to be alone because everything gets on my nerves currently. Everything.
