I'm sorry, I couldn't resist titling this post "feels." :p
For
 no good reason, I've felt very irritated the past few days. I've felt 
more "on edge" about things, and been a bit frustrated & stressed in
 general. I have no idea why. I don't know if it's the stress of school 
getting to me, or if it's some odd form of homesickness—but something's 
started gnawing away at me and I'm trying really hard not to let it 
dampen my attitude.
This has happened a couple of times before—my
 suddenly feeling irritated for no reason. Usually, after a lot of 
thought, I can pinpoint the source of it and deal with it. I'm hoping 
that in a couple days, I'll get over whatever weird frustration I'm 
feeling and go back to normal.
But it's funny, because being 
randomly irritated has reminded me how powerful our emotions can be. 
Being annoyed, by extension, makes me cranky, and being cranky makes me 
want to act more sarcastic towards people—it makes me want to sit in my 
room and mope all day—and it almost completely drains any motivation I 
have.
