You Just Don't Understand: Women and Men in Conversation https://www.amazon.com/dp/B007OWRBL8/ref=cm_sw_r_cp_api_dmiNFbT078YNS
Your emotional shift sounds very much like the result of testosterone. The term ‘roid rage came about because even men get more angry and aggressive on steroids.
Off the top of my head, be careful about doing other people's work for them. There is a tendency for women to support their male colleagues in ways that benefit the team but don't count towards their personal performance indicators, while men tend to focus on their their own role. The woman who is an equal but gets dumped with getting the coffee is the stereotype, which is recognisable enough to avoid. The less obvious things will be when you are expected to be in charge of moral boosting activities like organising get well cards, farewell parties, and other activities which are not part of your job description. This isn't necessarily conscious sexism but women tend to agree to this things more, so they get a reputation for it. And while this extra value added is appreciated generally, it isn't considered when assessing somebody for a raise. If it isn't in your job description, it isn't your priority.
When a co-worker tells you how stressed and busy they are with a task, instead of offering them a friendly ear to whine to, tell them how much more stressed and busy you are or lightheartedly joke about their time management skills and how they might need to come in on the weekend to catch up. Unless you are being paid as the workplace counselor, you don't need to encourage people to come and complain to you about their day.
This is an area I've been generally interested in for awhile, so plenty more tips where that came from. I'd say the best book I've read on the topic is by Deborah Tannen. She explains a lot of the intricacies of gendered discourse and she's one of the most respected academics on the topic. I also recommend Captivate by Vanessa Van Edwards.
