struggling....

I have had a tuff couple of nights.  My daughter is not sleeping well since she started nursery school.  The last 3 nights she has been up 4 times!  My head is killing me and I need sleep.  I am having diffiulty at work because I am so tired and moody.Also, we have a kid at school who is off his rocker...or at least off his meds.   I was asked to step in while this kid was swinging because we wanted to aviod restraining him.  For an 8 year old he is strong!  I was able to talk him down and not get hit.  On friday he ran out of the school and 5 teachers had to follow him (I am a special ed teacher in an elementary school).  Luckely I was able to talk him in.  What can I do?  I cannot retstrain this kid im my condition...what if he were to hit me in the stomach!  On top of that I don't want to tell anyone I am pregnant yet, I can't handle that.  I am supposed to go and get more PMT training (Physical Management Training) so I am going to have to tell someone that I just can't do this.  This mother has to stop playing around with this kids meds, she is royaly screwing him up!To top it off, yesterday marked what should have been my 28th week of pregnancy.  I really am missing the baby I lost:(  I am so worried about the baby I now have.
