Days are catching up on me

My days are catching up on me. I haven't even opened up my math today and was unable to do so until late the last two days.  Too much going on and my class is starting to suffer.  I've got to get back to getting it done early but this week has killed my schedule.  I am going to have to get it together now because I can't afford to fall behind on this stuff.  I will be completely lost and my grade will suffer.  I've also had to do homework with the boys every night and that chokes up a lot of time as well  It is difficult.  I am struggling.
