I have survived the first day of second semester. Which was surprisingly exhausting and bruising.
When I tried to describe why, I at first said it was because of imposter syndrome, which isn't quite right and got me encouragement of the form of 'But you're so smart, and not an imposter.'
It finally hit me that a) my choices for major etc were locked in now and b) I'm behind. Not in a way that I can't catch up-- but that does require me catching up. Which isn't a thing I'm looking forward to. (I actually got chased down by one of the lecturers after class to ask what subject I had taken, because he didn't recognise me, and when he found out I hadn't taken Magmatism and Metamorphism†, he let me know I was a little behind. In a way that I could catch up by reading a relevant textbook chapter, but still. And I have to notice I'm behind quickly.)
Also these classes involve a lot of reading. Which I'm not, like, thrilled by. Because now it's another thing to juggle outside of class. And they expect us to hit the ground running with that as well. (I have like, 6 chapters I need to read for one class, and while I appreciate they've cancelled some lectures to give us time to read that, that's still a lot.)
So I've done a lot today, from emailing people about a lit review, to starting the reading, to fighting Matlab licenses to the death. I even managed to write 1k words of recreational writing.
...and now I'm exhausted.
(And unnecessary geology fun fact: geology also uses the word 'epigenetic' and it is messing with my brain. If a syngenetic ore formed at the same time as it's host rock, and an epigenetic ore formed after it's host rock formed.)
† I'm particularly kicking myself over that, because I wanted to take that class last semester. I even could have, despite planning to do chem! But noooo, I decided to be ~sensible~ and didn't take it, and now it's kicking me in the arse a bit!
