I feel soo bad my emotions suck

I feel awful. I've had not the best day body aches and back aches and cramps and soreness and my poor little sister I just spased out on her because she forgot to get chilli sauce on my kebab and she mixed up the lamb shish and got chicken shish instead. I got so angry I threw the entire kebab at the wall and the dog helped herself to it. Poor girl went out and used her own money to get me a new one.  My anger seems to have such a short fuse since I've been pregnant and I cry so easy as well. I'm emotional
