Thank you both. To be honest, even just hearing from other people that they understand what I'm going through is a lot of help. It wasn't why I initially made this topic, but I still appreciate it a lot!

Anyway I'm working with some web-based productivity tools that might help me break up and prioritize everything I have to do. I hope to post about it eventually, and review what worked and what didn't, once I've sorted myself out a little better.

More suggestions (or if anyone wants to chime in on whether they deal with mental fatigue themselves?) are highly welcome, always.
