I'm day 3 and my anger is terrible. I actually made a post about it the other day. I've smashed an iPhone. I've nearly ended up in a fight. Today the SD card was messing about so I snapped it in rage. Lost about 8 years worth of photos ... oops.
I'm constantly agitated. It's horrible. The smallest thing can throw me over the edge. Deep breathing doesn't work. I just have to ride the storm and wait for it to pass. Told my wife to leave me alone today to avoid any unnecessary arguments. She wasn't happy but there's not much I can do.
I've no advice except to say I know how you feel and I'm currently searching the forum for anger related threads.
