Anyone else experiencing horrible mood swings like mine?

Ok so this is my first time being pregnant. I know your hormones are all out of place, and some people get terrible mood swings. Im not an angry person at all. Lately the past 2 weeks, everyone and everything has been making me furious! I get angry over the littlest things. Its making me mad. I had to go to a doctor appointment 2 weeks ago and one of the nurses asked me if everything was ok because I wasnt talking much. Im a shy person, and get emotional easily. I started to tear up when she said that. Then she said I seem pretty unsure about everything. I told her I was fine. Then she suggessted counciling, she tought I needed someone to talk to. Now that I was already at rage, because like I said the littlest things tick me off, I almost wanted to scream and walk out. I held in my anger, and told her I have 5 sisters, plenty of friends and family, if I had any problems, I could go to them if I needed to talk ever. I mean, whats it to her. My emotions are already mixed up over everything being overwhelming lately, why would she say something, after I clearly told her I was fine? I hope Im not the only one that has went through rough mood swings. I know this was pointless, but I just wanted to know if anyone else has been experiencing mood swings as bad as mine.
