Sorry to hear that. I get like that sometimes, too. That's when I post the most because I don't have energy for much else. That feeling would be fairly constant at the moment, given the state of the world, Palestine in particular, if I e.g. read the papers or watched the news. I mostly stopped looking, for that reason. It's okay to switch off from some things to gather your strength.

Try to take it easy sometimes if you can. Your studies are important and you want to do well, but you won't be able to keep it all up if you end up too burned out. Is there a more efficient way of studying? There might not be, but it's worth thinking about, just in case.
