Thomas AGAIN!

I really want the best in life for my son Thomas. He has ADHD and is impossible to control without his medicine. Previously he had been taking Adderall to help with the hyper behavior and to help him concentrate. His doctor took him off Adderall about two weeks ago and put him on Zoloft just to see how he does. Lucky for me he was in Colorado with his dad for this two weeks...when I picked Thomas up yesterday his dad informed me that Thomas wore him out...obviously the Zoloft is not working. Great...now what....I sent Thomas to school today as usual and warned his teacher about his extreme hyperness. Kevin picked Thomas up from school this afternoon and was confronted by Mr. Phillips (Thomas' teacher). Mr. Phillips said Thomas will not be allowed to attend his class anymore if his behavior does not improve. He is a disruption to the class and he can not teach the other students with Thomas in there. Today was the worst day Thomas has ever had. Apparently he was sent out into the hall and during that time he was disrupting other classes and teachers! Mr. Phillips suggested putting Thomas into a special class for kids with behavioral problems. This is not what I want for my son. I want him to go to school in a normal class with a normal teacher. He has already been labeled with ADHD I really don't want him to be labeled A BAD KID. I thought about home schooling him, can I commit to that? Can I really give him the education he needs? What about socialization. He needs interaction with other kids his age. I'm lost and I really wish I could just FIX this. All I can do is support him and let him know that we (our family) love him no matter what. I know things will get better for him and he will get the education he needs.
