The label stripped me of power to self-advocate

I had a nervous break when I just turned fifteen. I had been having issues for a year prior, and then it all came crashing down after my birthday at boarding school, during winter. My parents kept me at home for a couple weeks to see if my symptoms would abate, then sought a psychiatrist. I was then hospitalized because my parents thought I was sick enough. I recall being completely depressed, detached, and removed from reality. The confusion is whether or not I have Bipolar or Schizophrenia. My current label is Schizoaffective, which is a very confusing term and I don't really know if it's better or worse than schizophrenia or bipolar, but that it alludes to being on a spectrum. My first label was damaging, paranoid schizophrenia, because I felt pressured and had to fight against paranoia and was often patronized because of my eccentricities. I don't think the label helps people because it does nothing to qualify their experiences, nor the abuse they may experience in hospitals. Having the immediate label of schizophrenia after a label of psychosis NOS at the hospital left me powerless to self-advocate against the sexual assault and abuse I encountered because having psychosis means you can be put in grossly hostile situations, and experiences of verbal and physical assault get discounted because they'll just say you made it up. That's how it is detrimental. Knowing what your symptoms are is helpful, but the generalization and exaggerated label doesn't help much to end stigma nor help a victim of abuse. I know others who come from the war zone just to receive this diagnosis. I know my mom has severe depression and is now dealing with some psychotic symptoms. I don't doubt that I am struggling with some form of something, but the label doesn't explain it at all therefore causing more confusion and as a basis for injustice could exist.
