Really bad day yesterday

I've had my fair share of bad days associated with PD but yesterday topped them all.  I was having fits of anger all day long.  It wasn't directed at any one person or thing - it was just everything in general made me feel  angry.  I looked up the side affects of a pain medication called Tramadol so see if by chance it caused patients to feel angry but all it really said was that it caused some irritability and anxiety and mood changes.  I was attacking my friends and family on Facebook because of some of their comments made and I found myself posting things on my Facebook page that were kind of mean in nature.  I basically made it very clear that people who couldn't say anything nice in regards to a posting then they would be better off not saying anything at all. I also posted something on my Timeline that said "THIS IS MY FACEBOOK PAGE AND IF YOU DON'T LIKE WHAT I POST THEN UNFRIEND ME".  I have never been like that before.  I normally just take things in stride and when I feel the need to vent I do it through this group or to one of my best friends but never have I attacked other's for their opinions on a social media page.  
I am feeling a little less angry today so maybe today will be a good day.  I will try to stay positive in my comments and my thinking today.
