Stress management, my father was just admitted to the ER and released the next day. He is still having issues but his doc told him to come back in 2 weeks. He is having dementia problems, we are not sure if it is medication or if he is going to really suffer from dementia (please let it be a reaction to his medicine). I was up late and then up early for work, so needless to say everyone in my family was tired and stressed. I noticed the ease at which everyone would fall into a argumentative and blaming role. I kept telling myself that I was tired and stressed and to keep my mouth shut. It is interesting that I noticed this and made an effort to not be reactionary. I'm not saying I was perfect or great at it but I noticed and tried to change.
You can not change your past, but you can ruin a perfectly good present by worrying about the future.
