One thing everyone has overlooked is that CPS is bound by law not to reveal who called them. Thus, no matter who calls CPS, @sarah826‘s parents will not be told who called.
And if CPS is called, it isn’t the end of the world. An investigator will come out to the house and talk to your parents and then to the children separately from the parents. They may also talk to other adults in your life, such as teachers, pastors, and so on.
If the child or children are in no immediate danger no one would be removed from the home whether they decide to refer the case for follow up or not. If they do decide to refer a case for follow up, a case worker will be assigned and will come out to the house generally with a list of demands that need to be met. Since you are 13, your opinion and statements will be taken seriously.
I doubt that anything would get out to the newspapers or television because you are not in imminent danger, and it wouldn’t be a high-profile case, such as the recent cases where a child suffering from cancer or diabetes is denied medical treatment for religious reasons. If your parents agree to make sure you get appropriate medical treatment for your asthma and then do so, CPS will probably close the file after a few months.
However, as others mention, if you do end up in the ER because of a serious asthma attack, the hospital may be duty-bound to call CPS if abuse, including denial of medical treatment, is suspected.
I say all this because CPS has been called on us based on things my son claimed at school, as well as on a school employee’s personal dislike of me and what I insisted my son needed. Basically, they came to the house and offered help in a variety of ways, especially once they saw in our case that my son really does have a psychiatric diagnosis.
Good luck with everything. Asthma is a very real and potentially serious health problem, and it really does need to be treated, no matter what your parents think.
