The start of a New Week

Sunday night, trying to get everything for the next week at school.  Never seem to have the abilitiy to keep on task.  Everything seems to distract me.  I always seen to plan to get a lot done over the weekend, but then end up playing games or watching movies my husband puts on.  Why can't I stay on task and get my work done.  Why do I always get side tracked?  I just can't keep my mind on task.  How do I get my focus on work.  It is getting towards the end of the school year, and I have a lot to do. But I just can't seem to focus.  Is this because of the chronic pain?  Need to do something fast, it is effecting my job.  Time to go to bed and hopefuly sleep so I can face and get through another Monday.
