I'm not sure why but the last couple of days I've just felt so angry and argumentative, it may be hormonal as I'm due on next week but I'm never like this. I had a group meeting for a university assignment and I've been feeling fed up and stressed out about it. I'm a bit of a perfectionist, and I also have already got a degree and master's so I have quite high standards and good experience, and I'm trying to direct the project into the right direction but group members are disagreeing with me on every little thing. I've been very accepting and easygoing about it, but with the deadline approaching I've just lost patience and I found myself being assertive and disagreeing with group members, and explaining why.
As we were leaving the group then joked how they can't wait for this assignment to be over, and I've left feeling really guilty like I've soured the mood or made it more stressful. I'm usually quite passive, and very quiet. I feel embarrassed that I've come across poorly, although I think trying to look at it objectively I did say my opinions with a polite tone, the same way they were saying their opinions so I think I wasn't awful? Idk.
