jacobs bad day

ok jacob got sent home from school today for refusing to work with the resource teacher this is the first time it got real bad when he left miss payne tried to follow him and said she was going to work with him in his classroom. so he elbowed her . I do not know what to do.  he has never acted like that before and i feel he has a lable on him that will never go away now.  The one thing Idid do is asked to have him pulled from resource at leaste untill his therapy under way and he can handle the pressure I wish i had enought money to home school and get him some privite touters so that he does not have to fell so bad about himself at school all the time. I feel so inadaquite as a mother whis i could do better by him .
