I think I'm going crazy

Today I went to work. Problem about that is it was 6 hours later than I was supposed to. What makes me think that I have finally gone off the deep end is that I do not care. Normally in the priority of things in my life my job is number 2. It helps me get the other things that I need in life like food etc etc so it's very important. Why don't I care today? Is this going to last a while? Am I going to actually go into work Sunday when I don't care right now? I think I finally got so stressed that I snapped. I didn't feel anything snap. Yesterday I was me and today I'm a crazy person. Weird....
