Heya, I was wondering if you guys have experienced something similar: 

I was doing amazingly well recently and then yesterday, out of nowhere, I had a really bad ... episode, I guess. Insane anger resulting in shame resulting in anxiety resulting in anger..., the works... Over nothing, really. And I was even aware of not having a proper reason.
Now, today, I feel like shit. As in physically. I actually feel ok in my head.
I think I'm coming down with the flu. I mean proper flu, not just a cold. I just had a second look at my lunch etc.

So my question is if these two could be related? Does this happen to anyone?
