Any Ideas?

My precious Jarett cries at school on and off all day, begs not to go to church--hates the loud devo at church.  They had to come pull us out of class at church two weeks ago because Jarett was crying so much.  This, coming from the child who loves to play his drums really loud, enjoys singing, loved going to our old church, and loved music class at his "old school."  What do I do?  I can't stop crying about it.  I love my son so much.  Do we go to another church?  Do I pull him out of school?  I visited his class today, and went with him to Devo on Wed--he did fine with me there. Do I become this little guy's shadow?  Do I find counseling for he (and I)?  

I tried telling him that if he did good at school for a whole week, then we could go pick out a new toy at the store.  I told Macy, that she could have a toy for doing so well at her new school.  I plan to take him along for this adventure this afternoon--Macy will get a toy, Jarett will not.  Is this cruel?  I feel like maybe he is choosing to cry and be sad, and that he could choose to be happy, especially if Macy is rewarded for good behavior.

Maybe he needs to play with some new friends, so I invited a friend of his from church and school over to play last week--he loved that.  He tells me that he has friends that play with him and are nice to him at school.  However, his teachers informed me that, "the kids don't play with him when he is crying," and (on Tues), "he was crying so hard at lunch, that I thought he might throw-up."  WHAT???!!!!  This is not the son that I moved out of Texas?  Is this his response to moving?  His response to a new baby?  I am at a loss, but I desperately want to fix it.  I am praying that he can get over the hump.  Please pray with me, and leave me any comments that might help.
