Zoloft

My daughter has anxiety disorder which breaks into her school work. She use to be on Zoloft 50mgs she came off because her dr moved ot of state and it took a bit to get her back on it. After being off of it for 3 months she had a huge melt down and i took her to the ER i told them what was going on and they put her back on 50mgi called the school and told them. The caseworker four her IEP said if the meds would rise gradually. I told her I wouldn't know until we see her regular psychic on the 24th. U thought it was kind of a strange question. I'm also getting jkind of mad that when i told her my daughter is no longer on meds she said well that explains a lot. I feel very pressured baby the school not only to medicate my daughter but now also to up her meds. Not really by the whole school but mostly by this caseworker. My question is who do i go to about this issue and is there a chance her meds will go up? She is 9 also 10.
