I've definitely found that since starting T, my patience has diminished. It's happened a little bit while driving—not to the point of road rage, but definitely to the point that I definitely make more insulting comments to drivers that can't hear me (thank god) and I get pretty frustrated if someone is going 30 mph in a 35 lol. Also, I think I get the same way around my mom that you do around your coworker, but for different reasons. My mom is really prone to chatter and small talk to fill the silence, especially in cars, and if I'm not in the right mood (almost never) it just annoys the heck out of me. Sometimes I just want quiet time, y'know?
Also to touch on the active thing, I get really restless if I haven't worked out or done some sort of physical labour in a few consecutive days, so I totally feel you there. Sometimes I'm just itching to pick up an axe or shovel, but there's never enough to do with it!
Hope this helps!
