I have been struggling with sleep on and off for a couple of years now.  Sunday night I did not get much sleep at all.  I got 4 hours tops and I woke up and went to work a groggy mess.  I felt awful, and grumpy, and dissatisfied and like my life was miserable.  My AH and I have had some of the worst arguments when I am tired and exhausted.  I have made very poor decisions when I feel this way.  I can see this cycle that I used to run through.  My fatigue affects my mood, I interpret my bad mood as a fact.  I do things in this state that make my life harder or more unmanageable.  The problem is when I am tired I expect too much of myself.  I don't give myself the break I need.  I take other people's criticisms too hard.  I am too hard on myself.  And this is how I hurt myself.  Yesterday I recognized that I was tired and not just a wee bit tired but extremely fatigued.  Instead of beating myself up for not sleeping and pushing myself beyond my limits I decided to use the slogan "easy does it".  I actually allowed myself to have an off day.  I let my coworkers know I was struggling with fatigue and apologized for it in advance  (I had missed and forgotten a few things).  When I found myself bitter and frustrated with other people I didn't express it (not even in the passive aggressive ways I used to do that I thought were so clever but really weren't clever at all) and I reminded myself that I was tired.  When I started to think about all the problems in my marriage and how dissatisfied I was with it I tried to remind myself that it was likely the fatigue talking and I also decided not to argue or fight with my AH no matter what just for that day.  I decided that I could wait until tomorrow to make any important decisions or address any important issues.  I gave myself breaks, I rested, I took care of myself.  I pushed off work that didn't need my immediate attention.  I tried to stay in the moment.  I got through my day much more easily.  I was able to enjoy moments of my day.  I know it doesn't sound like much but for me it is.  In the past I would not even realize that my lack of sleep was affecting me.  I would have felt the negative feelings I was having yesterday and taken them as far as I possibly could.  I would likely have created some drama in my life by either expressing the negative feelings I was having as soon as they came to me.  Last night I slept well.  I woke up and I felt drastically different.  I was glad that I hadn't expressed the things I felt yesterday about my marriage or about my co worker and her lack of hard work etc.  This morning my perspective was much clearer.  There is one thing I need to address with my AH and I will address it tonight.  One issue.  Not several spiraling issues that are not connected.  Rather the most important of them all.  I feel better. So much better.  I was able to maintain my serenity during a time that is difficult and stressful to me.  I used to get up in the morning after a sleepless night dreading the day.  Knowing that it would be unmanageable but feeling I had no control over it.  Now I feel like I did have control over some things.  I had control over my actions that made my day more difficult.  What a change in my perspective.  I am so grateful to this program for that change.
