Feeling Agitated

Today I am feeling so agitated. Right now I feel like screaming, throwing stuff and punching holes in the walls. AHHHHHHH!

What is causing this? I can't think straight either. My fatigue has been really bad today because I pushed myself to go grocery shopping last night. I had no choice, downed some caffeine, just so I could stand up. I woke up in the middle of the night last night with swollen fingers, had to pee and was itching. My fingers get so swollen I can't even move my wedding ring when usually it is pretty loose.

I can't take this anymore!
